Giant magnetostrictive actuator

Several new giant magnetostrictive materials have been developed in recent years for actuation applications. Bulk rare-earth-iron alloys Terfenol-D present typical static magnetostrains of 1000... 2000 ppm, which permit the building of low-frequency actuators and transducers. New composite materials offer an interesting possibility for high frequency ultrasonic applications. More recently, rare-earth-iron thin films have been also explored for actuation in microsystems.
