Аннотация

A second-order precession of the magnetization vector in a normally magnetized magnetic plate
with a uniaxial anisotropy whose axis is tilted at an angle to the plate normal is considered. Under the conditions
for the orientational transition, precession pattern of the forced oscillation in the form of a large ring filled,
along the ring generator, with small rings is obtained. A relationship between the observed crowding and sparse-
ness of small rings and the tilt of the anisotropy axis to the normal to the plate plane is established and explained
on the basis of the potential-energy model. It is shown that the crowding and sparseness can be compensated
by a constant transverse field. It has been found that the phenomenon is critically sensitive to the axis orientation
and to the value of the anisotropy constant as well as to the strength of the constant field. It is indicated that the
observed phenomena can be put to practical use.
