摘要：

Modulation of the magnetic anisotropy by the electric field in epitaxial Fe3O4/PMN-PT multiferroic heterostructure is studied, which shows that the coercive field of Fe3O4 thin films can be decreased from 368 to 113 Oe by applying an electric field in PMN-PT [011] direction. Meanwhile, most shift of ferromagnetic resonance (FMR) field H-r(Delta H-r.[01 (1) over bar]) can reach up to -483 Oe by applying an external electric field.The giant shift of H-r from 251 to 9681 Oe is obtained as the sample rotated from theta = 90 degrees (H//[01 (1) over bar ]to theta = 0 degrees (H//[100]) when the electric field was applied in Fe3O4/PMN-PT heterostructure. [GRAPHICS] . IMPACT STATEMENT A giant shift of ferromagnetic resonance field was obtained by simultaneously applying an external electric field and a rotating sample along axes both parallel and perpendicular to the magnetic field.
