Influence of Shape Anisotropy on Magnetization Dynamics Driven by Spin Hall Effect

Figure 4

Magnetization oscillating trajectory with different current densities for in-plane free layer with initial state . Higher current density leads to oscillation with larger cone angle and finally switching. The free layer size is 40 nm × 20 nm × 1.5 nm, with = 7.93 × 10¹⁰ A/m² and = 9.05 × 10¹⁰ A/m².
