Strain Engineering of Magnetic Anisotropy in Epitaxial Films of Cobalt Ferrite

Hiroshige Onoda, Hiroaki Sukegawa, Jun-ichiro Inoue +1

Perpendicular magnetic anisotropy (PMA) energy up to $K_{\mathrm{u}}=6.1\pm 0.8$ MJ m${}^{-3}$ is demonstrated in this study by inducing large lattice-distortion exceeding 3% at room…
