Analysis of wasp-waisted hysteresis loops in magnetic rocks
arXiv:1201.0065 · doi:10.1103/PhysRevE.85.011124
Abstract
The random-field Ising model of hysteresis is generalized to dilute magnets and solved on a Bethe lattice. Exact expressions for the major and minor hysteresis loops are obtained. In the strongly dilute limit the model provides a simple and useful understanding of the shapes of hysteresis loops in magnetic rock samples.
