Abstract

A vibrating sample magnetometer for measurements at high magnetic fields and high temperatures (HT-VSM) was developed. The first-order antiferro-ferromagnetic phase (AFM-FM) transition in B2 FeRh alloy was investigated using the HT-VSM in a wide range of temperatures and magnetic field regions. At 300 K, we succeeded in observing a field-induced AFM-FM transition by magnetization measurements up to 19 T. The transition field decreases with increasing sample temperature.
