摘要：

A simple approximate equation of motion for the longitudinal component of the magnetic moment of a single-domain uniaxial superparamagnetic particle is proposed. This equation is used to evaluate the spectral density function of the interparticle magnetic motion at finite temperatures and to describe the stochastic resonance effect. The correspondence of the results obtained with those of previous calculations is discussed.
