摘要：

The ribbons with different Ga contents were prepared by the melt-spun method. The maximum magnetostriction of -2100 ppm has been obtained in the ribbons with 17 at% Ga. The microstructures of ribbons were determined by XRD and HRTEM. It was found that DO3 structure and Ga-rich clusters emerge in those ribbons of Fe83Ga17 with wheel speed of 12 m/s. The Ga-rich clusters and modified DO3 structure result in a giant magnetostriction of Fe-Ga alloy ribbons. (c) 2006 Elsevier B.V. All rights reserved.
