Effect of twin microstructure changes on the magnetization behavior and magnetic forces in Ni–Mn–Ga-based ferromagnetic shape memory alloys
Chem. Met. Alloys 6 (2013) 177-182
The effect of twin microstructure changes on the magnetization behavior and magnetic forces in Ni–Mn–Ga-based Ferromagnetic Shape Memory Alloys (FMSMA’s) is discussed on the basis of the recently developed micromagnetic theory of magnetization processes in this new class of magnetostrictive materials. A comparison between theoretical results and experiments on the superelastic behavior of Ni–Mn–Ga in an external magnetic field is also made.
