Method for Measuring the Magnetic Properties of Permanent Magnets at High Temperatures by Using Pulsed Magnetic Fields

Abstract

A device for controlling the temperature of a sample was installed in a high-field magnetometer using pulsed magnetic fields that we developed. The magnetic properties of various permanent magnets, including high-performance magnets, were measured with this system from room temperature to 200°C. The magnetic properties at high temperatures were successfully measured, as well as those at room temperatures.
