Abstract

In order to accurately design magnetic devices that are used at high temperature, it is necessary to understand the behavior of several magnetic materials at high temperature. However, the precise measurement of magnetic properties at around Curie temperature is difficult, because the permeability is near to that of air and the preparation of measuring setup having an insulation which can be used at around 800 °C is not easy. In this paper, the magnetic properties of several magnetic materials until Curie temperature are measured. It is shown that the change of iron loss of cold rolled steel sheet SPCC with the temperature is more remarkable than that of electrical steel sheet.
