Material Notes:

Ni50Mn28.5Ga21.5 single crystal. The magnetic shape memory phenomenon is produced by magnetic-field-induced rearrangement of (ferromagnetic) twinned martensite microstructure accompanied by a large macroscopic deformation. The magnetic field/strain curve can be altered by surface treatment.Applications:ActuatorsBreaker switches/fusesEnergy harvestersVibration dampersSensors
