Interaction Field Distribution in Longitudinal and Perpendicular Structured Particulate Media

In this paper, a systematic analysis of the interaction field distribution as a function of the magnetic state in structured longitudinal and perpendicular media was discussed. In order to obtain results with statistical significance, a modified version of the Ising model was used. In certain states the interaction fields applied to all the particles and have represented the histogram of these interaction fields have been calculated and compared with the FORC diagram. Usually these histograms were represented in the saturation states, in the positive remanent saturation state and in the DC demagnetized state. To calculate the magnetic state a standard Monte-Carlo-Metropolis algorithm was used. These results were evidencing the need of profound knowledge of the interaction which affects the particles in a structured material during any magnetization process.
