General Description : This material is a single crystal of Nickel-Manganese-Gallium. When placed in a magnetic field there is a magnetic-field-induced rearrangement of (ferromagnetic) twinned martensite microstructure accompanied by a large macroscopic deformation. This effectively gives up to 6% fully reversible growth perpendicular to the magnetic field, and allows this material to be used as an actuator, with cycle times of up to 1-2kHz. Similar in action to piezo-based or magnetostrictive materials, this material however produces much higher strain outputs (typically 10 to 100 times more) and higher energy density (8 to 50 times higher). Typical applications include actuators, energy harvesters, vibration dampers and sensors.
