International audienceEnvironmental requirements currently placed on magnetic materials that are used in both domestic and professional electromagnetic devices are becoming more stringent. The growing demand for components to operate under extreme environmental conditions prompted this study of the effect of temperature variation on magnetic materials. Thus, the knowledge of their behavior, especially under high temperatures, is of prime importance. In this paper, two methods for determining the evolution of Jiles-Atherton model parameters with temperature are presented. The parameters evolution of the model as a function of temperature is discussed. Both methods are compared

Some soft magnetic materials are strongly dependent of the temperature, because of their low Curie temperature. In order to predict their behavior in electrical devices, engineers need hysteresis models able to take into account the temperature. This paper is an attempt to take into account the temperature in an existing model of static hysteresis through its parameters. Variations of some parameters with temperature are issued or build thanks to the literature. At the end, all needed parameters have an analytical law versus temperature. Simulation results are compared to measurements and discussed.
