- Abstract
- Magnetic shape memory alloys give significant recoverable strain due to the reorientation of martensite plates by the motion of twin boundaries as a result of an applied magnetic field. The presence or extent of the effect is a function of such variables as the martensite morphology, the mobility of twin boundaries, the volume magnetostriction, and the magnetic susceptibility. The effect can occur at high frequencies and at easily achievable temperatures. These materials thus show great promise for use in actuators and sensors for a variety of applications. An introduction to this class of materials is provided, and preliminary work to synthesize and characterize nickel-based magnetic shape memory materials is described.
