Polarization-induced anisotropic damping in Co/[Pb (Mg_(1/3)Nb_(2/3))O_3]_(0.7)-[PbTiO_3]_(0.3) (011) heterostructure

摘要

This study investigates the magnetic dynamics of a ferroelectric/ferromagnetic heterostructure mediated by a charge/strain-induced magnetoelectric interaction that exhibits a pronounced dynamic magnetic response to an electric field. In the experimental process, the epitaxial strain gave rise to electrically tunable uniaxial magnetic anisotropy, and spin accumulation at the interface led to large anisotropic damping with a C_(2v), symmetry. The results show the significant potential for applications of composite multiferroics and provide a feasible approach for high-performance devices that rely on electrically controlled magnetism.
