The studies on giant magnetostrictive （GMS） thin films all over the world are reviewed in this paper. The preparation and property characterization of GMS thin films are introduced. The magnetostrictive and magnetic properties and their influencing factors of TbDyFe single layer films, including composition, stress, heat-treatment and substrate temperature, are described. The compositions and structures of GMS multilayer films are reviewd in detail. The influencing factors of the magnetostrictive and magnetic properties of GMS multilayer films in low field are discussed, including heat-treatment, induced magnetic field, layer thickness, as well as how they affecting the properties of GMS multilayer films. The status and trend of GMS thin films are proposed and prospected.
