Magnetostriction is an important magnetic property of soft magnetic materials, which provides different kinds of applications. Low- and high-magnetostriction materials are of interest. For reducing noise in transformers and electric machines, low-magnetostriction materials are desired. However, for sensors and actuator applications, high-magnetostriction materials are the target. In conjunction with magnetostriction, other magnetic properties need to be suitable for applications such as high permeability and low coercive force. A review of the most promising materials will be presented. In order to understand the high magnetostriction in Fe-based alloys, the lecture focuses on its microscopic origin while building on microscopic investigations. Low magnetostrictive material Fe-Si will also be discussed. Results of magnetic properties on a new low magnetostrictive alloy, Fe-Ti, will be presented.
