Figure 4. Temperature and magnetic anisotropy dependence of VCMA effect in the Ru/CFA/MgO heterostructures.

Figure 4

(a) The dependence of Kut on applied electric field at different temperatures. (b) Temperature dependence of interfacial magnetic anisotropy at zero voltage. (c,d) The VCMA coefficient ξ as a function of (c) temperature and (d) magnetic anisotropy for the CFA film in the negative and positive bias regions. The solid lines in (b) and (c) are fitted curves by power laws of Ms(T) with exponents (b) γ = 2.00 ± 0.08 and (c) γ′ = 1.89 ± 0.29, respectively.
