2019年4月29日 · In BiFeO3, a well-known room temperature multiferroic, the competition between various exchange interactions manifests itself as non-collinear spin order, i.e., an incommensurate spin...

Through a combination of in-plane and out-of-plane electrical switching, coupled with ab initio studies, we have discovered that the epitaxy from the substrate imposes a magnetoelastic anisotropy...

2024年4月4日 · Using nitrogen vacancy-based diamond magnetometry, we observe the magnetic spin cycloid structure of BiFeO 3 in real space. This structure is magnetoelectrically coupled through symmetry to the ferroelectric polarization and this relationship is maintained through electric field switching.

2014年10月9日 · Initially, Zalesskii et al reported a possible distorted spin cycloid structure from 57 Fe NMR experiments (NMR peak shapes give information about spatially modulated spin structures). The authors observed highly anisotropic profiles in BiFeO 3 samples and interpreted this as evidence of distorted spin cycloid structure with an elliptic ...

2023年11月16日 · The magnetic moments in BiFeO3 are arranged into a spin cycloid, resulting in unique magnetic properties which are tied to the ferroelectric order. Previous understanding of this coupling has relied on average, mesoscale measurements to infer behavior.

2023年2月10日 · Beyond its various properties, the model multiferroic BiFeO 3 (BFO) displays a rich magnetic structure illustrated in the bulk by its long period (∼62 nm) spin cycloidal modulation. Here, BFO nanoparticles are produced by a facile hydrothermal method and show average size of 8 nm and a narrow size distribution, as determined using x-ray ...

2024年12月11日 · In this study the structural and magnetic properties of Nd-doped BiFeO 3 materials with the formula Bi 1-x Nd x FeO 3 (x = 0–0.2) were investigated. Samples were prepared using the sol-gel method and annealed at 823 K for 4 h.

2020年9月21日 · An important characteristic of BiFeO 3 is its noncollinear magnetic order; namely, a long-period incommensurate spin cycloid. Here, the progress in understanding this fascinating aspect of BiFeO 3 is reviewed, with a focus on epitaxial films.
