From: Voltage-Controlled Magnetic Anisotropy in Fe1−xCox/Pd/MgO system
(a) Typical resonant frequencies of MSSWs of Fe/Fe1−xCox/Pd/MgO with x = 1 (Fe/Co(0.3 nm)/Pd(0.2 nm)/MgO) under an in-plane magnetic field (Hext). The black dots and red line represent the experimental and fitting data using Eq. 1, respectively. (b) Fourfold crystalline anisotropy field Hcry (dashed line) and interfacial magnetic anisotropy Hint (red rectangles); the error bars represent the standard deviation of the anisotropy field obtained by the root-mean-square method. The value of x represents the fraction of Co in Fe1−xCox.
