Summary: Polycrystalline Ba0.75Pb0.25Ti1-xFexO3 (0 <= x <= 0.148) (BPTF) ceramics were synthesized using the sol-gel auto combustion method. The structural, vibrational, electrical, and magnetic properties were investigated. The presence of both tetragonal and hexagonal phases was observed, with an increase in the hexagonal phase in higher Fe-doped samples. A relaxor-type phase transition was observed in the high Fe-doped samples. The samples exhibited ferroelectric properties at room temperature, as confirmed by the presence of room-temperature P-E hysteresis loops. Additionally, higher Fe-doped samples showed increased ferromagnetic ordering at room temperature. Therefore, the Fe-doped Ba0.75Pb0.25TiO3 system exhibited multiferroic properties at room temperature.

Summary: This study proposes a method to efficiently control 2D magnets with a small electric field in a multiferroic heterostructure. The feasibility of this strategy is demonstrated in the bilayer CrI3/BiFeO3(001) heterostructure using first-principles calculations. The heterostructure exhibits strong magnetoelectric coupling, allowing efficient switching between ferromagnetic and antiferromagnetic states of the bilayer CrI3 by the polarized states of BiFeO3(001).

Summary: This work systematically studies the structural, electronic, and optical properties of a 2D ferroelectric Ga2O3 bilayer system. It reveals the high tunability of the bilayer system under interlayer perturbation and biaxial strain, as well as a phase transition from vdW to ionic interlayer interaction induced by in-plane biaxial tensile strain. These insights hold significant prospects for experimental synthesis, characterization, and application of 2D Ga2O3 atomically thin layered systems.

Summary: This article demonstrates that the elastic strains at the interface in layered structures of thin cobalt, nickel, and permendur layers on ferroelectric ceramics substrates have a more significant impact on the magnetoelectric effect than the magnetostriction of the ferromagnetic layer. These structures, obtained through ion-beam sputtering and planarization, exhibit higher magnetoelectric voltage coefficient for cobalt than for nickel and permendur. They also have thermosability within the temperature range of 25 to +120 degrees Celsius and reproducible magnetoelectric properties, making them suitable for magnetoelectric converters and magnetic field sensors.

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.
