Abstract

The magnetic domain structures of the cubic parent phase (high-temperature phase) in ferromagnetic shape memory alloys (SMAs) have been studied by electron holography. In a Ni₅₁Fe₂₂Ga₁₇ alloy, the magnetic flux distribution in the parent phase changes dramatically before the onset of martensitic transformation. In contrast, a Ni₄₅Co ₅Mn_36.7In_13.3 alloy - a recently developed ferromagnetic SMA - does not show appreciable changes in the magnetic domain structure upon cooling. The anomaly observed in the Ni₅₁Fe ₂₂Ga₁₇ alloy appears to be due to lattice distortions, which become more pronounced as the temperature approaches the martensitic transformation start temperature, Ms.
