Ferromagnetic Shape Memory Materials: Underlying Physics and Practical Importance
The underlying physics of the giant magnetic or mechanical field-induced-strains in Ni–Mn–Ga alloys are briefly discussed. For the purpose of illustrating some fundamental aspects, experimental data relative to lattice instability and composition dependence of magnetization are presented alongside reported results. An implementation of Ni–Mn–Ga single crystal as a strain sensor is described.
