In this paper, the superelastic motion of twin boundaries in the martensitic phase of Ni2MnGa with magnetic fields of 8 kOe applied at 265 K was found to be associated with the staining.Abstract:
Strains of nearly 0.2% have been induced along [001] in unstressed crystals of Ni2MnGa with magnetic fields of 8 kOe applied at 265 K. These stains are associated with the superelastic motion of twin boundaries in the martensitic phase that is stable below about 274 K.read more

Sanjay Singh,K. R. A. Ziebeck,E. Suard,Parasmani Rajput,S. C. Bhardwaj,A. M. Awasthi,Sudipto Roy Barman +6 more
TL;DR: In this article, the magnetic moment in the martensite phase is higher compared to Ni2MnGa, which is in good agreement with magnetization measurement, which indicates that it is likely to exhibit magnetic field induced strain.

Ferromagnetic materials
TL;DR: In this paper, the authors restrict their attention to the ferrites and a few other closely related materials, which are more closely related to anti-ferromagnetic substances than they are to ferromagnetics in which the magnetization results from the parallel alignment of all the magnetic moments present.
