| Abstract: | The nonlinear dynamics of an ensemble of single-domain interacting particles upon excitation by radio-frequency pulses of a magnetic field is investigated. Reorientation of magnetic moments of ensemble particles under the effect of the pulses of the radio-frequency field is observed. The effect of varying the magnetic structure on the frequency dependences of susceptibility is studied. Temporal characteristics of precession in separate particles under the conditions of an orientation transition are considered. |
