Spin transfer torque magnetization reversal in a hard/soft composite structures

Spin transfer torque magnetization reversal in a hard/soft composite structures

Current induced magnetization manipulation in a spin valve structure where the free layer is a magnetic hard/soft composite structure is studied using micromagnetic simulations. In this structure where the hard layers has strong perpendicular magnetic anisotropy, a domain wall can be nucleated in th...
