Modeling of Magnetic Properties of Rare-Earth Hard Magnets

Magnetic properties of hard magnets are currently attracting a great deal attention. In the paper, modified Harrison model was used to describe saturating hysteresis loops three praseodymium–dysprosium ribbons that differed in their chemical composition and processing conditions. Microstructural studies (TEM diffraction patterns) were performed for under consideration. The incorporates number physically tangible concepts such as anhysteretic curve, bifurcations, bi-stability. modification original approach consisted adding an additional degree freedom modeling by freeing restraints present version, which both coercivity remanence functions temperature only.
