TLDR
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

Effect of internal stress and bias field on the transformation strain of the Heusler alloy Ni52Mn24.4Ga23.6

TL;DR: In this paper, the effects of internal stress and bias field on transformation strain in the Heusler alloy Ni52Mn24.4Ga23.6 were investigated and it was found that residual internal stress caused by the directional solidification during the growth and additional bias field with a direction consistent with the intrinsic preferential orientation would provide favorable conditions for exhibiting large transformation strain and magnetic-field-induced strain capability.

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.
