Intensity of electromagnetic energy radiation by a quiescent ferromagnetic spherical particle placed in a permanent magnetic field

摘要

The classical problem of calculating the energy of electromagnetic energy radiated from a ferromagnetic particle is solved for the case when the vector of spontaneous magnetization M of the ferromagnet differs from that of external permanent magnetic field H (0). The dependence of electromagnetic radiation intensity on the product kappa R (where kappa = omega(0)/c is the wavevector, R is the radius of the particle, and omega(0) = gamma (e) H (0) is the precession frequency of transverse component M (aSyen) of the magnetization (M = M (aSyen), M (z) )) is derived.
