Summary: This study reports an observation of more than an order of magnitude increase in saturation magnetization in BiFeO3/Ag nanocomposites at room temperature compared to bare BiFeO3 nanoparticles. The specific self-assembly pattern of BiFeO3 and Ag nanoparticles, as well as the charge transfer between Ag and O, are found to be responsible for this significant rise in room-temperature magnetization. The findings have implications for various applications, including biomedical uses.

Summary: We observe a clear converse magnetoelectric effect at room temperature in ternary BiFeO3-based systems near the morphotropic phase boundary (MPB). In situ XRD diffraction under different electric fields reveals that lattice distortion and phase transitions dominate the observed effect. This finding provides experimental proof and an explanation for electric-field control of magnetism at the MPB, potentially enabling the design of low power consumption magnetoelectric devices.

Summary: This study investigates the low-temperature phase transitions observed in magneto-electric bismuth ferrite by connecting recent structural revelations with X-band electron paramagnetic resonance spectra. The research shows the vital role of oxygen vacancies in lattice contraction and spin reorientation, contributing to the anomalies in resonant lines. The phase transitions at 140, 200, and 280 K are explained by changes in interatomic distances, elastic distortion of oxygen octahedra, and freezing of spins in the lattice, respectively.

Summary: Nanoparticles of Ti-doped ferroelectric BiFeO3 were synthesized and densified via a low-temperature sintering process, resulting in dense ceramics with a relative density over 90%. Ti doping effectively decreased the concentration of Fe4+ in the ceramics, leading to suppression of the extrinsic dielectric responses.

Summary: Integrating materials characteristics through constructing artificial superlattices has led to the successful synthesis of BiFeO3/BiMnO3 SLs with considerable ferroelectric polarizations and tunable magnetic moments. The tunable magnetic moments of SLs are closely linked to the dimensionality of BiFeO3 layers, with the superexchange interaction of Fe-O-Mn in SLs tending towards antiferromagnetic rather than ferromagnetic as the dimensionality of BiFeO3 per period is reduced. This interlayer modulation effect in SLs offers an attractive way to precisely control multiple order parameters in a multiferroic oxide system.
