Abstract
Change in the magnetic domain structure of Ni2MnGa Heusler alloy with the structural transformation from the parent phase to the intermediate phase and subsequent transformation to the martensite was studied by in situ observations using Lorentz microscopy and electron holography. Both the parent phase and the intermediate phase showed peculiar stripe magnetic domains, and the observed magnetization distribution was similar to each other. In contrast, the magnetization distribution was dramatically modified by the transformation to the tetragonal martensite. The observation appears to indicate that the magnetization distribution in the parent phase can interact with the short-wave lattice distortions to generate the intermediate phase, via the magnetoelastic interaction, resulting in the inheritance of the original magnetization distribution into the intermediate phase.
