Investigation on ferromagnetic shape memory alloys [PDF]

open access: yesScience and Technology of Advanced Materials, 2005
Ferromagnetic shape memory alloys, exhibiting large recoverable strain and rapid frequency response, appear to be promising shape memory actuator material. These materials exhibit large shape memory effect associating with martensitic transformation, and magnetic-field-induced strain in the martensite state.

Theoretical prediction and experimental study of a ferromagnetic shape memory alloy: Ga_2MnNi [PDF]

open access: yes, 2008
We predict the existence of a new ferromagnetic shape memory alloy Ga_2MnNi using density functional theory. The martensitic start temperature (T_M) is found to be approximately proportional to the stabilization energy of the martensitic phase ...

Phase stability and magnetic-field-induced martensitic transformation in Mn-rich NiMnSn alloys

open access: yesAIP Advances, 2012
A series of Ni50-xMn41+xSn9 (x = 0–19) alloys from Ni-rich to Mn-rich composition were prepared, and the composition dependence of phase transitions and magnetic properties were investigated. No γ-phase can be observed until x = 17.
