▲ [18p-PB1-72] Voltage induced coercivity change of Co film grown on Cr2O3 barrier
Keywords:voltage control of magnetic anisotropy (VCMA), spintronics, Cr2O3
Co-based ferromagnetic materials exhibit large perpendicular magnetic anisotropy and are promising candidates for voltage control of magnetic anisotropy (VCMA) materials. In this study, voltage-induced coercivity change of Co film grown on corundum-type Cr2O3 was investigated. The Cr2O3 thin film prepared by the radical-assisted molecular beam epitaxy method exhibit dielectric properties comparable to a thicker film even with a film thickness of 30 nm. In the Pt/Cr2O3/Co/Pt structure, obvious coercivity change due to voltage application was observed.
