A Co-Sputtering Process Optimization for the Preparation of FeGaB Alloy Magnetostrictive Thin Films

Nanomaterials, 2023
A co-sputtering process for the deposition of Fe0.8Ga0.2B alloy magnetostrictive thin films is studied in this paper. The soft magnetic performance of Fe0.8Ga0.2B thin films is modulated by the direct-current (DC) sputtering power of an FeGa target and ...
