Electrodeposition of Supermalloy Thin Films: Structural and Magnetic Characterization

We have prepared supermalloy (Ni-Fe-Mo) thin films using electrodeposition method. In this work electrodeposition of supermalloy took place in a single electrolyte containing Ni+2, Fe+2, and Mo+2 ions, under potentiostatic control (constant potential). Scanning Electron Microscopy (SEM) and Energy Dispersive X-ray analysis (EDX) techniques were employed to investigate the morphology and chemical composition of the films. The result indicates that the weight percent (wt. %) of Ni and Mo, decreases by increasing the film thickness while the weight percent of Fe, increases as the film thickness increases. The magnetic properties of the supermalloy films have also been studied using alternating gradient force magnetometer (AGFM).
