Summary: Multiferroic BiFeO3-NiO (BFO-NiO) nanocomposites were synthesized using sol-gel route and characterized for their multiferroic-magnetoelectric properties. The composite exhibited enhanced magnetism and exchange bias effect due to the interactions between antiferromagnetic and ferromagnetic exchange couplings. The temperature-dependent magnetic measurements showed a transition from superparamagnetic behavior to quantum superparamagnetic state at low temperature. The nanocomposites demonstrated considerable suitable for various device applications such as information storage, magnetic random access memory, and bio-sensing.

Summary: The full control of multiferroic interfacial magnetism using an electric field is a challenging task for MEMS and has the potential to revolutionize electronics operation mechanisms. By combining highly correlated ferroic orders and interfacial magnetoelectric interactions, devices beyond CMOS can be achieved. These devices utilize electric fields to regulate magnetization, leading to downsizing, improved performance, and reduced power consumption. This review summarizes recent advances in voltage control of interfacial magnetism with different material systems and gating methods, demonstrating five classic mechanisms and discussing the potential of controlling skyrmions and 2D material magnetization. The results indicate the universal applicability of E-field gating and predict significant progress in spintronics.

Summary: The nonvolatile voltage control of resistance in Co/MgO/CoFeB magnetic tunnel junctions demonstrated in this study originates from the nonvolatile magnetization rotation of an interacting CoFeB magnet driven by volatile voltage-generated strain. The findings suggest that the magnetization response to volatile strain among interacting magnets is different from that among isolated magnets.

Summary: This paper demonstrates an extraordinarily elevated fourfold anisotropic magnetoresistance (AMR) in 3d-5d heterostructures and uncovers the contributions of biaxial magnetic anisotropy and spin-flop transition to the signal. The subtle interaction of pseudospin coupling with the lattice and external magnetic field captured in this emerging phenomenon holds great potential in AFM spintronics.

Summary: Tuning and controlling the magnetic properties of nanomaterials is crucial for implementing new technologies. In this study, core/shell Ni@(NiO, Ni(OH)2) nanowire arrays were fabricated using an electrochemical approach, and their magnetic properties were characterized. The results showed surface oxidation-induced magnetic hardening in the nanowires and an increasing exchange bias effect at low temperatures.

Summary: This study demonstrates the synthesis of high-quality single-phase chromium oxynitride thin films using in-situ nitrogen doping, which exhibits robust ferromagnetic and insulating state. By increasing nitrogen content, the crystal structure changes and saturation magnetization decreases significantly. The authors also achieve a large and controllable exchange bias field in the chromia heterostructures through synthetic anion engineering, reflecting potential applications in modern magnetic sensors and read heads.

Summary: Recent studies have shown that antiferromagnetic insulators efficiently support spin current. In this study, we observe a strong temperature dependence and reversed sign of dampinglike spin-orbit torque (SOT) in Pt/NiO/CoFeB, which is different from the slight variation with temperature observed in Pt/CoFeB bilayer. The negative dampinglike SOT at low temperatures is proposed to be mediated by magnetic interactions tied to the "exchange bias" in Pt/NiO/CoFeB, in contrast to the thermal-magnon-mediated scenario at high temperatures. These results highlight the potential to control SOT by tuning the magnetic structure in multilayers.

Summary: The study demonstrates the encapsulation of sea urchin-like Ni nanoparticles with BaTiO3 nanoparticles to achieve a room temperature ME coupled Ni@BaTiO3 system. The magnetic, electric and magnetoelectric properties of the Ni nanoparticles partially coated with BaTiO3 provide evidence of ME coupling between Ni and BaTiO3 at their interface. The obtained magnetoelectric coupling coefficient of the Ni@BaTiO3 composite is 225 μV cm^-1 Oe^-1, showing the potential for designing strongly coupled multiferroic memory devices and sensors.

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.
