Abstract:
Magnetic field driven phase transformation material is a class of smart material which combines the functional behaviors of ferroelastic shape memory and magnetostriction. The large magnetic fieldinduced strain obtained in magnetic field driven phase transformation materials can be achieved through two mechanisms, which include reorientation of martensitic variants caused by the magnetic field induced twin boundary motion and shape memory effect via magnetic field induced first order phase transformation. Heuslertype Ni Mn X ( X= Ga or In) magnetic field driven phase transformation alloys are potential candidates for magnetic sensors and actuators, owing to their large magnetic fieldinduced strain, high energy density and rapid response and so on. The research progresses of magnetic fielddriven phase transformation materials, including Ni Mn Ga alloys, Ni Co Mn In alloys and antiferromagnets, are summarized. And recent researches from our group are introduced, which are focused on in situ studies of magnetic field driven phase transformation materials using highenergy xray diffraction and neutron scattering techniques. At last, future trends of magnetic field driven phase transformation alloy are prospected.
