Abstract

[Truncated abstract] Since the discovery of Ni2MnGa ferromagnetic shape memory alloys some 15 years ago, intensive research has been conducted to search and develop new and more powerful magnetically activated shape memory alloys. The effort has been severely hampered by the low magnetic driving force, intrinsically limited by the magnitude of magnetic crystallographic anisotropy, for mechanical actuation. The discovery of metamagnetic phase transformation in Ni-Mn-Z (Z=In,Sn,Sb) system in 2004, with their large magnetization difference across the transformation, made a breakthrough and brought new promise for creating magnetically activated shape memory alloys.
