Abstract

The magnetic field-induced strain (MFIS) of the martensite metallic compound Fe-31.2% Pd (at.%) and Fe₃Pt were studied in a pulsed magnetic field using the capacitance method at low temperatures in a martensitic phase, which is much lower than the martensitic transformation temperature T_M. After zero field cooling, pulse magnetic field was applied parallel to [001]_p axis. Large MFIS has been measured. The value of the MFIS ΔL/L is 0.4 % expansion, 1.7 % compression, respectively. When the magnetic field was decreased, the recovery of the strain of Fe₃Pt 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.
