Magnetic and Electromagnetic Effects

A new medium magnetization model that takes account of the magnetic interaction of particles has been developed. It is based on the curling magnetization reversal model, and incorporates Atherton’s function for the mean field interaction. It is very easy to build the mean field function into the algorithm of our medium model. It was shown that the new medium model is very effective for fitting not only the MH loops but also the remanence characteristics of longitudinally oriented Ba-ferrite tape. It is expected that more precise simulation analyses will become possible through the use of this medium model.
