Abstract:
The effect of easy-plane anisotropy on the damping of the nonlinear magnetization oscillations that accompany 90$^\circ$ pulsed magnetization of magnetic films and plates is analyzed numerically. It is shown that the magnetization time can be decreased to $\sim$ 0.5 ns at an effective anisotropy field $H_{Kp}\ge$ 6 kOe and that magnetization oscillations are fully damped at $H_{Kp}\ge$ 20–40 kOe. The magnetization time can be $\sim$ 0.15–0.20 ns at a magnetizing pulse amplitude $H_m\sim$ 20–40 Oe.
