摘要：
Magnetization dynamics of a soft magnetic layer with perpendicular anisotropy under spin transfer torque from two adjacent layers is investigated. One of these two spin polarized layers has its magnetization fixed while the second one has its magnetization oscillating at a frequency f. It is observed that the soft layer magnetization could switch only for a range of frequency around an optimal value f(o). The value of f(o) is strongly dependent on the intrinsic properties of the soft layer and the applied electric current. This scheme could solve the problem of overwritability in multi-bit per cell magnetic random access memory and bring momentum to research in magnetic memory for high storage capacity.
