Abstract
The magnetic moment response of an isolated nanoparticle of a uniaxial anisotropy and plane lattice composed of nanoparticles is being studied under the action of a longitudinal alternating field and a Gaussian pulse with an additional noise signal. The modes of partial and complete magnetization reversal of dipole systems implemented only in the presence of noise have been revealed. The periodic dependence of the magnetic moment response and magnetization reversal processes on the pulse duration has been studied. The conditions under which the pulsed magnetization reversal is most and least sensitive to the action of the noise signal have been revealed.
