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

TL;DR: In this article, the authors report on calorimetric measurements under hydrostatic pressure in a series of composition related metamagnetic shape memory alloys, and show that the pressure-induced entropy changes at moderate pressures are in the range of those reported for giant caloric materials.

Hysteresis effects in the magnetic-field-induced reverse martensitic transition in magnetic shape-memory alloys
TL;DR: In this paper, the authors studied the mechanism of magnetic-field-induced reverse martensitic transformations by considering the field-induced temperature-shifts in the thermal hysteresis loop of the magnetization and critical fields determined from magnetization isotherms.

Frequency Response of Acoustic-Assisted Ni–Mn–Ga Ferromagnetic- Shape-Memory-Alloy Actuator
TL;DR: In this article, an acoustic-assist technique was applied to the actuator to enhance its performance, which increased the reversible magnetic-field-induced strain (MFIS) by up to 100% (increase from 0.017 to 0.03 at 10 Hz).

Correlation between reentrant spin glass behavior and the magnetic order?disorder transition of the martensite phase in Ni?Co?Mn?Sb Heusler alloys
TL;DR: The strength of the RSG state is critically dependent on the sharpness of the magnetic transition at (T(M)(C)).

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.
