초록
Magnetostrictive materials are deformed by applying magnetic fields as electrostrictive materials are deformed by applying electric fields. The GMA(Giant Magnetostrictive Alloy: Terfenol-D) shows larger strain and force compared with piezoceramics and SMA. It is expected that the GMA replaces the piezoceramics in various applications. In this paper, the basic properties of GMA and the current trends of its application are introduced.
