Summary: This research focuses on nonvolatile electrical control of magnetism in 2D van der Waals materials, specifically by designing a multiferroic heterostructure with a CrOBr ferromagnetic bilayer and an In2Se3 ferroelectric monolayer. The weaker interlayer exchange coupling in the CrOBr bilayer allows for easier regulation by ferroelectric polarization, enabling reversible shifts between ferromagnetic and antiferromagnetic ordering. This electrically controlled interlayer magnetic coupling may have practical applications in high-sensitivity sensors and high-density data storage using 2D vdW bilayer magnets.

Summary: The kinetic magnetoelectric effect, an orbital analog of the Edelstein effect, provides an additional degree of freedom to control magnetization through charge current. Researchers have demonstrated this effect in topological insulators, identifying Cu2ZnSnSe4 as a potential candidate. The effect depends on surface details and shows significant potential in Chern insulators and Z(2) topological insulators compared to metals due to surface current flow.

Summary: The introduction of defects is the key method to control the multiferroic properties of one-dimensional frustration Ca3CoMnO6. In this study, a series of Ga3+ doped Ca3CoMn1-xGaxO6 (x = 0, 0.05, 0.1, 0.2) compounds were synthesized and their crystallographic structure, magnetism, and dielectric properties were characterized. The XRD patterns confirmed the rhombohedral structure of all samples. Ga3+ ions exhibited obvious inhibitory effect on the magnetic short-range order. Substituting Mn4+ with Ga3+ suppressed the polar nanodomains and reduced the diffusion index gamma. The consistent signs of Delta epsilon and Delta tan delta in the magnetic field dependent permittivity suggested the intrinsic magnetoelectric coupling effect in Ca3CoMn1-xGaxO6. The freezing process in the Ca3CoMn1-xGaxO6 system was primarily controlled by the coupling of the polar nanodomains.

Summary: Multiferroic materials composed of ferromagnetic and ferroelectric components are interesting for technological applications due to sizable magnetoelectric coupling allowing the control of magnetic properties by electric fields. Recent studies have predicted a strong charge-mediated magnetoelectric coupling in a Ni/HfO2 multiferroic heterostructure. The magnetoelectric effect is found to be very sensitive to the interface stoichiometry, with a reversal occurring if an oxidized Ni monolayer is formed at the interface.

Summary: The universality of 2D multiferroics in the Ca-based double-perovskite bilayer system has been demonstrated, showing that the breaking of inversion symmetry correlation between initial and final polarization states is crucial for achieving the transition of magnetization. Only the switching of tilt distortion can cause a change in the direction of magnetization, making multistep switching of tilt distortion via ferroelectric switching the lowest energy barrier pathway for controlling magnetization by an electric field.

Summary: This paper investigates the magneto-electric coupling in freestanding BiFeO3 using optical second harmonic generation combined with varying magnetic field and temperature. The authors find that the coupling is suppressed by strain releasing but remains robust against thermal fluctuations. Magneto-electric coupling, with the potential to enhance device functionality and reduce energy consumption, has been challenging to probe in unstable and fragile freestanding membranes or two-dimensional materials.

Summary: Based on first-principles calculations, this study reveals that the magnetoelectric coupling in Fe3Ga/HfO2/Fe3Ga heterojunction is induced by polarization, rather than the common strain-mediated magnetoelectric effect. The interfaces between Fe3Ga and HfO2 play a crucial role in the polarization-induced magnetoelectric effect.
