Asymmetric excitation of the two-order magnetization precession under orientational transition conditions

Abstract

The forced nonlinear precession of magnetization vector in the normally magnetized magnetic plate is examined. Investigations are performed under orientational transition conditions at the asymmetric orientations of transverse and longitudinal ac fields. It has been revealed that the precession of equilibrium position exhibits pulse like behavior under the action of two types of field. This feature manifests itself as the nonuniform bunchings of phase trajectories in the precession pattern. It is demonstrated that the nonunifor mity of precession can be compensated by applying the asymmetric dc field. It should be emphasized that the compensation is highly sensitive to the dc field amplitude and reaches several hundredths of a percent of its total value. Recommendations are given to observe the discussed phenomena in the experiment. The possi bility of their practical application is discussed.
