Self-activated reversibility in the magnetically induced reorientation of martensitic variants in ferromagnetic Ni-Mn-Ga films
Abstract
Magnetically induced reorientation (MIR) of twin variants for [101]-oriented martensite has been studied for Ni-Mn-Ga thin films deposited on (001) YSZ substrates. The MIR effect displayed by these films is self-reversible, is characterized by a small increase in the magnetization, and shows a temperature-dependent activation field. These properties can be described in terms of a magnetic microstructure comprised of MIR-active and MIR-inactive …
