Magnetic phase-transformation material
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.
