As a scientific experiment platform, a novel high temperature magnetization measurement system in pulsed magnetic field has been developed. In this paper, the thermal insulation design, measurement system and magnet are presented. A thermal analysis and a heating test have been carried out in the temperature range of 300 K-1060 K. Using the thermal insulation, the temperature of the pick-up coils can be maintained below 450 K when the sample is heated to 1060 K and the magnet is immersed in 77 K liquid nitrogen. Finally, a magnetization measurement of La 2/3Ca 1/3MnO 3 in a 15 T pulsed magnetic field at the temperature of 300 K, 350 K and 520 K has been carried out. It is evident that the magnetization of the sample significantly decreases with a rise of temperature. © 2011 IEEE.
