Abstract

The magnetic field-induced strain (MFIS) of the martensite metallic compound Fe3Pt were studied in a pulsed magnetic field using the capacitance method at low temperatures down to 4.2 K in a martensitic phase, which is much lower than the martensitic transformation temperature TM = 85 K. After zero field cooling, pulse magnetic field with the maximum frequency of 160 Hz was applied parallel to [001]p axis. Large MFIS has been measured. The value of the MFIS is ΔL/L = −1.7 %. When the magnetic field was decreased, the recovery of the strain was observed. At the 2nd shot, the strain of about 0.6 % was observed. It means that MFIS occurs even in short-pulse magnetic fields.
