Summary: HoFeWO6 exhibits multiferroicity and magnetoelectric (ME) coupling, with electric polarization onset at 17.8 K and antiferromagnetic ordering. The compound shows metamagnetic behavior at low temperatures directly related to dielectric properties, with a magnetocapacitance (MC) effect observed. X-ray diffraction results confirm the noncentrosymmetric polar structure and suggest Fe3+ cations are antiferromagnetically ordered in a noncollinear fashion. The observed MC effect, change in polarization by magnetic field, and direct correspondence with magnetization support strong ME coupling in HoFeWO6.

Summary: Composite multiferroic materials, due to their unique magnetoelectric coupling effect, have significant potential in multifunctional devices. This study presents a novel composite multiferroic material system called multiferroic fluids, which are created by dispersing multiferroic particles in an insulating base fluid and exhibit a strong magnetoelectric coupling effect under external fields. The magnetoelectric coupling effect is achieved through the arrangement of multiferroic particles into chain-like structures under magnetic or electric fields, resulting in induced polarization. Based on their magnetoelectric and rheological properties, multiferroic fluids are believed to have potential applications in various fields such as magnetoelectric storage, sensors, and photovoltaics, but further research is needed.

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 investigates the electrical modulation of magnetic states in single-phase multiferroic materials using domain-wall magnetoelectric (ME) coupling. Results show that the domain-wall ME effect is dramatically enhanced when the separation between ferroelectric (FE) domain walls shrinks below the characteristic width of the antiferromagnetic (AFM) domain walls. These findings suggest that the domain-wall ME effect is capable of electrical control of magnetization.

Summary: The study demonstrates that magnetoelectric coupling can be significantly enhanced in specific heterostructures by simultaneously applying multiple strain engineering approaches. This enhancement is achieved by optimizing magnetization reorientation through magnetic anisotropy strain and the use of multilayered magnetic materials, as well as modifying domain-mediated magnetization switching through voltage-induced magnetoelastic anisotropy. The findings of this research are important for realizing energy-efficient magnetoelectric applications.

Summary: Experimental realization of thin films with significant room-temperature magnetoelectric coupling coefficient α(ME) without an external DC magnetic field has been challenging. Here, large α(ME) of 750 +/- 30 mV Oe(-1) cm(-1) is achieved in multiferroic polymer nanocomposites (MPCs) thin films. The MPCs consist of PMMA-grafted cobalt-ferrite nanoparticles uniformly dispersed in piezoelectric polymer P(VDF-TrFE). Nanoparticle agglomeration is reduced by surface functionalization with PMMA, enabling the uniform dispersion of nanoparticles in submicrometer thin films. This research can promote the development of flexible and printable multiferroic electronic devices for sensing and memory applications.

Summary: A bilayer nano-stanene-like structure with Ruderman-Kittel-Kasuya-Yoshida (RKKY) coupling described by the Ising model is proposed. The study uses effective-field theory with correlations to investigate the magnetic and thermodynamic properties. It is found that the exchange coupling, longitudinal magnetic field, number of non-magnetic layers, and anisotropies significantly influence the magnetization, specific heat, and internal energy. Different saturation magnetizations are observed on the magnetization curve. The variation in the system blocking temperature is also studied. These results provide theoretical guidance for the magnetic investigation of nanomaterials with RKKY coupling.

Summary: Unique magnetic behavior of a Kagome-like nanoparticle with a ferromagnetic exchange coupling described by the mixed-spin (5/2, 3/2) Ising model was studied using effective-field theory with correlations. The magnetization, specific heat, and magnetization plateaus were found to be influenced by exchange coupling, transverse magnetic field, and anisotropies. The magnetization reversal was observed as magnetization plateaus on the magnetization curves. Magnetic susceptibility and specific heat curves showed interesting two-peak behavior due to the influence of various parameters. Possible cases of depressed saturation magnetization in the Kagome-like nanoparticle were also examined.

Summary: The mixed spin-5/2 and spin-1 Ising model is introduced to describe two trimer-decorated graphene-like nanoparticles. The magnetic behaviors of these models are studied using an effective field theory incorporating correlations. Several distinct features are observed when considering typical parameters, such as simultaneous transverse magnetic field and anisotropy. The stability of magnetizations is determined by the principle of lowest energy, while the compensation and multiple phase temperatures for magnetization curves depend on various physical parameters. Finally, the dynamic magnetic behavior of the system under periodically oscillating magnetic field is reported.

Summary: Deposition of Pd/Pt/Au three-layer films on p-GaN under high and ultra-high vacuum conditions was studied to investigate the electrical contact properties. Linear I-V curves were observed in samples deposited under ultra-high vacuum conditions, while nonlinear I-V characteristics were obtained in samples deposited under high vacuum conditions. The study also found that the samples deposited under high vacuum conditions had higher amounts of oxygen and Pd oxide. The oxide layer had an additional influence on the electrical characteristics of the Pd/Pt/Au/p-GaN contact.

Summary: The corrosion behavior and microstructural evolution of Sc microalloyed Al-3.2Cu-1.5Li alloys were investigated in detail. The microstructural results showed higher levels of dislocations density in the Sc microalloyed sample, which resulted in significantly refined grains and T1 precipitates. Microalloying with Sc changed the corrosion mode of the alloy and localized corrosion was found to occur preferentially at the subgrain within unrecrystallized grains with high grain stored energy.
