Abstract :
The gyromagnetic switching behavior of a single-domain grain or particle with uniaxial magnetocrystalline and shape anisotropy is solved analytically by the gyromagnetic torque equation using physically plausible Gilbert damping. 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 magnetization during damped precession is derived
