Abstract:
Giant magnetostrictive materials are new functional materials developed since 1970’s, characterized by giant magnetostrain and powerful energy conversion. In this paper, an introduction of magnetostriction and the history of giant magnetostrictive materials, and a number of important research results obtained by our scientists in the field are described firstly. Then we review the recent developments of both rare earth and non rare earth magnetostrictive materials. Finally, the tendency of developing the giant magnetostrictive materials is presented.
