Abstract
Parametric plots of the remagnetization versus demagnetization remanences were found for four metallic ferromagnets-nickel wire, two types of AlNiCo, and samarium cobalt 2:17. These plots, known as Henkel plots, were compared to Wohlfarth's model for noninteracting magnetic particles and several Preisach models. The remagnetization data were taken with a variety of paths to the net zero magnetization state. The resulting Henkel plots exhibit similarities to independent Monte Carlo simulations. The differences can be mostly explained by considering that the magnetization in the metallic ferromagnets occur by domain wall motion.
