The minimum switching field threshold and switching speed are key parameters for the magnetic recording in writing. This paper presents the dynamic precession of the moments of the grains based on LL equation.Under microwave-assisted reversal conditions, the influence of the differences between the angle of Anisotropy field on the magnetic moment reversal and loading speed of reversal magnetic field in two interacting particles is investigated.
