An analysis of the magnetization reversal process (particulate media)

A mathematical model is proposed in order to analyze interparticle interactions of particulate recording media, and the physical nature of the Henkel plot is investigated. The magnetization of a noninteracting particles assembly is described by an integral of the distribution of the switching field of isolated particles, and interparticle interactions are described as magnetic field modifications at the integral's upper boundary. The calculated Henkel plot, assuming the normal distribution as the distribution of the switching field, is in agreement with the experimental data.<
