Magnetic phase-transformation material

Abstract

A magnetic phase-transformation material with the formula Nia−mMnb−nCom+nTic is provided, wherein a+b+c=100, 20<a≦90, 5≦b<50, 5≦c≦30, 0≦m≦a, 0≦n≦b, 0<m+n<a+b, and wherein, any one or combination of a, b, c, m, n represent an atomic percentage content. The magnetic phase-transformation material has properties of high toughness, high deformation rate, ferromagnetism and magnetic field-driven martensitic phase transformation, which can be widely used in various fields including high-strength and high-toughness actuators, temperature and/or magnetic sensitive elements, magnetic refrigeration devices and equipments, magnetic heat pump devices, magnetic memories, micro-electromechanical devices and systems, and thermomagnetic power generators or transducers.
