Figure 5: Variations of anisotropy and out-of-plane magnetization during macrospin trajectories.
From: Non-volatile electrically-driven repeatable magnetization reversal with no applied magnetic field
For (a) and (b) in Fig. 4, we plot the voltage-driven strain-mediated changes in K, and the resulting changes in Mz/Ms, as functions of time t. We also plot the resulting and only component of the anisotropy field (2K/μ0Ms)cosθ in terms of the corresponding flux density. Equilibrium positions 1, 2 and 3, and the blue and pink dots at ramp ends, correspond to Fig. 4.
