There are several ways in which a magnetoelectric effect can arise microscopically in a material. In crystals, spin–orbit coupling is responsible for single-ion magnetocrystalline anisotropy which determines preferential axes for the orientation of the spins (such as easy axes). An external electric field may change the local symmetry seen by magnetic ions and affect both the strength of the anisotropy and the direction of the easy axes. Thus, single-ion anisotropy can couple an ext… WebFeb 7, 2024 · Efficient manipulation of antiferromagnetic (AF) domains and domain walls has opened up new avenues of research towards ultrafast, high-density spintronic devices.
