【Abstract】 Rare-earth giant magnetostrictive materials (GMM) are a type of new functional materials. A brief description is given of the history of giant magnetostrictive materials; and their characteristics are compared with those of piezoelectric materials. Current research developments are described, in particular: (1) fabrication technology, includingthe Czochraski, FSZ, Bridgman, powder-sintering and powder-bonding methods; (2) composition studies of GMM, including the substitution for Fe in RFe 2 and exploitation of light rare-earth GMM. Applications and the importance of GMM research in China are reviewed.更多还原
