Characterization and modelling of temperature influence on global magnetic properties
Résumé
Nowadays, more and more electrical devices are working with high stresses (mechanical, thermal, electrical, ...). This paper focuses on the thermal stress. The aim of this paper is to first, study the global behaviour of the temperature on standard static magnetic properties. In a second time, we use a Jiles-Atherton model, in order to reproduce the static hysteresis loops obtained with measure for a large class of magnetic materials samples. For each temperature, the five model parameters are optimized. The model parameters variation is also discussed.
