Summary: The study reveals that the linear magnetoelectric effect allows for selection or switching between antiferromagnetic states through the application of electric and magnetic fields, which are preserved by energy barriers. Experimental results show that the field and temperature variation of the coercive field for switching is similar to the theoretical model. Investigation into the dynamics of antiferromagnetic domain switching confirms a power-law frequency dependence, indicating one-dimensional domain wall propagation.

Summary: Type-II multiferroics show large magnetoelectric coupling and are promising for new device functionalities. We report a new multiferroic material, BiMn3Cr4O12, where an antiferromagnetic phase is induced by the structural change at the ferroelectric phase transition. Thermodynamic, dielectric, and pyroelectric studies reveal that the ferroelectric critical temperature corresponds to the Ne'el temperature of the Cr3+ spins, and an increase in ferroelectric polarization is observed below the Ne'el temperature of the Mn3+ spins.

Summary: Intentional subtraction of Fe ions in NiFe2O4 induces spin canting and enhances magnetoelectric coupling, while also generating ferroelectricity. The peak enhancement in magnetoelectric coupling strength is observed when about 30% of Fe ions are subtracted, after which further removal of Fe ions affects the material's structure.

Summary: This research demonstrates the successful induction of conical magnetic structure in BaFe12O19 by introducing a nonzero DM interaction through partial substitution of Fe3+ sites, leading to direct ME and magnetodielectric coupling in In-doped BaFe12O19 ceramics. Additionally, BaZn0.9Zr0.9Fe10.2O19 ceramics exhibit noncollinear magnetic structure and direct ME coupling due to larger Zn2+ and Zr4+ ions preferring the spin-down sites. The results provide a feasible approach to develop multiferroic and magnetoelectric coupling in ubiquitous M-type hexaferrite.

Summary: This study demonstrates a significant resonance amplification of the ME effect by incorporating Ni-Mn-Ga particles into P(VDF-TrFE) piezopolymer, resulting in a giant ME coefficient of 6.05 V.cm(-1) under specific magnetic fields. The physical mechanism behind this enhancement involves the volume magnetostriction of the magnetostrictive particles and the resonant elastic oscillation of the piezoelectric polymer matrix.

Summary: Evaluation of the bidirectional magnetoelectric effect in a BiFeO3/NiFeCuMo bilayer demonstrates that the electronically controlled ME effect and magnetically controlled ME effect have separate origins. The magnetically controlled ME effect is attributed to the cycloidal magnetic structure of the bulk BFO, while the electronically controlled ME effect is achieved through electric-field-induced ferroelectric polarization switching. The bidirectional ME effect is a result of the combination of the cycloidal magnetic structure throughout the film and an uncompensated weak ferromagnetic interface near the BFO/NiFeCuMo interface.

Summary: This study synthesized nanocomposites (NCs) containing SrFe12O19 and Bi0.9Dy0.1FeO3, where Dy-substitution increased the magnetization and dielectric constant of BiFeO3 (BFO), while increasing SFO content in the NCs led to higher magnetization but lower dielectric constant. The changes in capacitance of the NC samples in the presence of a magnetic field up to 150 kOe indicated a substantial enhancement of the magnetoelectric (ME) coupling coefficient of BFO in the nanocomposites, which tended to improve with higher SFO content in the NCs.

Summary: Through experimental and modeling results, we have discovered a unique tetragonal-to-orthorhombic-to-tetragonal phase transformation induced under low electric fields (< 1 kV/mm) in grains with 002 crystallographic poles oriented either within 20 degrees or orthogonal to the applied electric-field direction in a polycrystalline Pb-free piezoceramic. In contrast, grains with their 002 poles oriented 30 degrees- 80 degrees to the electric-field direction undergo a continuous tetragonal-to-orthorhombic transformation for electric fields larger than 1 kV/mm. These findings highlight the critical role of a phase-transition-assisted domain switching mechanism in grains of specific orientations towards achieving a large electrostrain coefficient of d(33)* similar to 600 pm/V under low electric fields (< 1 kV/mm) in the Pb-free Sn-doped (Ba,Ca)(Zr,Ti)O-3 piezoceramic.

This study both tests the applicability of lattice strain matching in brittle materials and explores a novel fabrication approach for in-situ composites via eutectic solidification.

Summary: This paper explores the impact of land use change on energy-related CO2 emissions using multi-dimension metrics. The results indicate that the scale of land use types has a bidirectional effect on emissions; land use mixture in mature city agglomerations has a significant suppressive effect; land use intensity is associated with emissions in most cities, with adverse effects spreading from west to northeast. Therefore, it is suggested to regulate land transaction, promote mixed land use, and utilize renewable energy to reduce energy footprints and mitigate emissions.

Summary: A sustainable FeOF nanocomposite with extraordinary performance has been developed in this study. Compared to the current mono-valence intercalation LiCoO2, it exhibits a specific capacity and energy of 621 mAh g(-1) and 1124 Wh kg(-1), respectively, which is three times the specific capacity and double the specific energy. The (de)lithiation process is made reversible by combining nanostructured FeOF with graphene, providing interparticle electric conduction. This breakthrough represents a significant progress in developing sustainable conversion materials, eventually overcoming the driving range and cost barriers.

Summary: This study investigates the potential of NiSi metal in high-temperature antiferromagnetic spintronics. It reveals high-temperature antiferromagnetism in single-crystal NiSi with a Neel temperature above 700 K. The antiferromagnetic order in NiSi has non-centrosymmetric magnetic character and a small ferromagnetic component in the a-c plane. Furthermore, NiSi exhibits different magnetic and electronic hysteresis responses to field applications due to the disparity in two moment directions, and these switching behaviors persist to high temperature. These findings highlight the importance of NiSi in the pursuit of antiferromagnetic spintronics.

Summary: Studying the flow behavior of amorphous solids is crucial for understanding their deformation mechanism, but detecting basic flow events in these materials is challenging. Using simultaneous SAXS/WAXS experiments, researchers have identified elementary flow carriers in wound metallic glasses, with a radius of gyration ranging from 2.5 to 3.5 nm, based on flow-induced structural heterogeneities. The size of these carriers increases and their morphology changes from spherical to rod-like during flow. Additionally, the atomic structure undergoes an unusual change to a more disordered state during winding/annealing at a temperature around 0.8 Tg. This work provides an atomic-to-nanoscale description of flow carriers in amorphous solids during deformation.

Summary: Fe-based metallic glasses are promising materials in the fields of advanced magnetism and sensors. This study proposes a novel approach to tailor the amorphous structure through liquid-liquid phase transition, and provides insights into the correlation between structural disorder and magnetic order. The results show that the liquid-liquid phase transition can induce more locally ordered nanodomains, leading to stronger exchange interactions and increased saturation magnetization. The increased local heterogeneity also enhances magnetic anisotropy, resulting in a better stress-impedance effect.
