Summary: This study demonstrates a method to reverse the electric polarization of multiferroic materials by applying and removing a magnetic field, which requires two cycles to bring the system back to its original configuration. During this process, the system visits four states with different magnetic configurations, with half of the spins undergoing unidirectional full-circle rotation in increments of about 90 degrees. Therefore, this material exhibits a peculiar magnetoelectric switching behavior that converts the variations of the magnetic field into circular spin motion.

Summary: Magnetoelectric (ME) sensors are important tools for detecting weak magnetic fields, but there are currently no high-quality ME sensors available for high-temperature environments. By bonding a specific piezoelectric ceramic and alloy together using an inorganic glue, a high-temperature ME sensor with excellent piezoelectric performance and maximum stress was achieved. The sensor also exhibited high magnetic field detecting precision at different temperatures.

Summary: This paper analyzes the influence of hard and soft admixture on the functional properties of multiferroic ceramic composites. Two composite materials were synthesized via solid-state reaction route, with PZT-type materials as the ferroelectric component and nickel-zinc ferrite as the magnetic component. It is found that the type of doping (soft vs hard admixture) has significant effects on the dielectric, ferroelectric, electromechanical, magnetic, and magnetoelectric properties of the composites. PZT with a soft admixture shows advantages in terms of effective polarization and high magnetoelectric effect, while PZT with a hard admixture demonstrates better stability of physical parameters.

Summary: Bulk BaTiO3-xCoFe2O4 (x = 0.1 - 0.6) magnetoelectric composites with high purity and excellent dielectric and magnetic properties were prepared using the phosphate bonded ceramics approach. The dielectric properties were influenced by composition-dependent relaxations and anomalies at different frequencies, while the magnetic properties were limited by the size of CoFe2O4 particles. The measured direct magnetoelectric coupling coefficient was higher than that of conventionally sintered ceramics and comparable to that of core-shell structures.

Summary: This study quantitatively analyzed the magnetoelectric particulate composite material system and revealed the main mechanisms responsible for the below-optimal performance of this class of materials. The experimental characterization of the composite demonstrated its multifunctional properties and quantified the interrelationship between composition and performance. The study found that the addition of magnetic particles improved the mechanical and electrical properties of the composite, but particle mobility had a detrimental effect on the overall magnetoelectric coupling performance.

Summary: Electric-field control of magnetism is crucial for the next generation of data storage technology. Researchers have explored the electric-field control of magnetism via strain coupling, especially in heterostructures like CoFeB/PMN-PT. Recent experiments in magnetic tunnel junctions/FE architecture show promising results in nonvolatile and reversible electric-field control of tunneling magnetoresistance, indicating great potential for future data storage technology.

Summary: Organic-inorganic hybrid (OIH) halide perovskite is a promising material in the field of semiconductors, and efforts have been made to design new lead-free OIH halides for optoelectronic applications. We have synthesized a perovskitoid compound and an antiperovskite compound with unique structures and properties. The perovskitoid compound displays switchable dielectric property, while the antiperovskite compound exhibits higher photoluminescence quantum yield and magnetic properties. This structure-property relationship in OIH manganese halides will contribute to the design of new perovskites and antiperovskites.

Summary: In this study, two organic-inorganic hybrid halides were synthesized and the role of halogen bonding was revealed. The first compound showed a unique type-II halogen bonding between organic and inorganic ions, leading to structural changes and modulation of photophysical properties. The second compound demonstrated dual-band emission, possibly due to energy transfer from the organic amine to Mn centers. The role of halogen bonding was explored through quantitative electron density analysis and intermolecular interaction energies.

Summary: Type-II multiferroics often have lower polarization values than Type-I multiferroics, which requires the use of pyrocurrent measurements. However, this method becomes inadequate when faster dipole relaxation and thermally stimulated free charge carriers overshadow the magnitude of the pyrocurrent. This study demonstrates the effectiveness of the DC bias current technique in overcoming this limitation and characterizing type-II multiferroic materials with small polarization.

Summary: Efforts have been made to design multifunctional lead-free organic-inorganic hybrid (OIH) halide compounds, which are considered as next-generation solar cell materials. However, it is challenging to design OIH halides that exhibit both long-range magnetic ordering and high photoluminescence quantum yield (PLQY) due to the contrasting effect of the compounds' dimensionality. In this study, we demonstrated an approach to enhance PLQY in two-dimensional (2D) Heisenberg antiferromagnets by increasing the alkylene chain length of [H3N-(CH2)(m)-NH3]MnCl4 compounds. These compounds showed long-range antiferromagnetic ordering and an increase in PLQY with increasing spacer cation length. The findings provide insight into the design of new OIH halides with desirable magnetic ordering and PLQY.

Summary: We conducted a comprehensive and comparative study on the structural, static, dynamic, and nonequilibrium magnetic properties of the polymorphs of LiFeSnO4. It was found that LiFeSnO4 exhibits two polymorphs, an orthorhombic phase (HT) and a hexagonal phase (LT), which differ in their crystal structures and magnetic properties. Both polymorphs show spin glass behavior and the presence of an exchange bias effect due to magnetic inhomogeneity.

Magnetic studies revealed antiferromagnetic or ferromagnetic interactions in different compounds. This research demonstrates the diversity of copper-containing compounds in extended framework structures.

Summary: In this paper, the authors used the distance between the states as a theoretical measure to determine the bipartite entanglement in a one-dimensional magnetic dimer system. The calculation was compared with the concurrence, a well-known entanglement measure, and found to be the same. Experimental verification was done on single crystals of copper acetate, showing the existence of bipartite entanglement even at room temperature. Characterization and calculations revealed the weak intermolecular interactions and low probability of direct Cu-Cu exchange in copper acetate.

Summary: We report the unconventional and interesting multiferroic behavior of a layered noncentrosymmetric ferrimagnetic spin-1/2 system Bi2Cu5B4O14. Neutron powder-diffraction study reveals a robust ferrimagnetic (up arrow down arrow down arrow down arrow down arrow) ordering below TC = 25 K, which remains unaffected even under a high magnetic field of H = 10 T. Interestingly, two successive ferroelectric transitions are observed, one triggered by the magnetostriction effect at TC = TE2 = 25 K and another caused by a structural distortion at TE1 = 32 K.

Summary: In this paper, the field-induced ferroelectricity in BaHoFeO4 within a narrow range of applied magnetic fields (1.5 T H 5 T) is reported. Magnetization measurements reveal magnetic anomalies at TFe ordering of Fe3+, a possible spin structure change of Fe3+, and the antiferromagnetic ordering of Ho3+ sublattices. Heat capacity data did not show any anomaly at TNFe, but exhibited a broad N . Isothermal magnetization measurements indicate a metamagnetic transition at 1.5 T below 40 K. Temperature-dependent dielectric measurements below 1 T reveal two anomalies corresponding to Ho3+ ordering and a possible change in the magnetic phase of the Fe sublattice. These anomalies disappear at higher magnetic fields, and a different dielectric anomaly appears above the metamagnetic transition. A switchable electric polarization appears below 25 K and above the metamagnetic transition field (H 1.5 T), but disappears above 5 T.
