In my research, I was faced with the need to study the process of magnetization and magnetization reversal of an ensemble of single-domain particles.

In the works known to me, the theory is based on the Preisach scalar model. I have hardly found any works that would consider an ensemble of multi-axis single-domain particles. I think I managed to find a solution to this problem. 1. Maybe I missed something? 2. How relevant is this topic at the moment?
