Simulation of high-frequency information recording on single domain particles

The paper considers the nonlinear dynamics of an ensemble of single-domain interacting particles under the influence of a radio-frequency pulse of a magnetic field. The possibility of reorientation of magnetization vectors upon excitation by radio-frequency pulse was demonstrated. Changes in the electromagnetic response from the ensemble of particles was investigated. The analysis of the responses spectra of the ensemble of particles perfomed. A splitting of the spectrum under the influence of a radio pulse of a magnetic field was revealed.
