ROTATION OF THE MAGNETIZATION VECTOR OF A MONODOMAIN PARTICLE UNDER THE ACTION OF A HIGH-FREQUENCY FIELD PULSE

We obtained a numerical solution of the modified Hilbert equation describing rotation of the mag-
netization vector in a high-frequency field of large amplitude. Based on this solution, we have studied rotation
of the magnetization vector of a spherical ferromagnetic monodomain particle, possessing a cubic anisotropy,
from the direction parallel to an easy magnetization axis to the perpendicular direction under the action of a
high-frequency magnetic field pulse. The amplitudes and the interval of frequencies of the magnetic field capa-
ble of rotating the particle magnetization vector are determined.
