▲ [16a-C41-8] Effects of fluorine introduction on the voltage control of ferromagnetic CoFeB/Al2O3 interface magnetic anisotropy

〇(M2)Mykhailo Pankieiev1, Koji Kita1 (1.Univ. of Tokyo)

Keywords:Perpendicular magnetic anisotropy, Voltage control, Fluorine

Addition of thin fluoride layer to CoFeB/Al2O3 stack increases perpendicular magnetic anisotropy (PMA) at the interface, saving the possibility of voltage control of magnetization direction. Optimal stack structure for maximazing PMA was found. Also ferromagnetic thickness dependence of anisotropy enegy was obtained and coefficient of interface anisotropy energy to applied electric field calculated.
