Damped gyromagnetic switching

The gyromagnetic switching behavior of a single-domain grain or particle wi th uniaxial magnetocrystalline and shape anisotropy is solved analytically by the gyromagnetic torque equation using physically plausible Gilbert damp ing. The sole restriction is that the anisotropy easy axis and the applied field be collinear. The analytical solution for the magnetization switching time is then used to calculate precisely various phenomena which occur in pulsed-current stripline testing of magnetic recording storage media. Also, the analytic relationship between the polar and azimuthal angles of the ma gnetization during damped precession is derived.
