چکیده :

In this paper, a straightforward method of depositing graphene-oxide (GO) on sputtered permalloy thin film was presented. After sputtering the permalloy thin film on a copper substrate, electrophoresis as an affordable methodology was utilized to deposit a thin film of GO on the permalloy film in liquid phase. Afterwards, the structural, morphological, magnetic and elemental characteristics of the sputtered permalloy thin film and electrophoretic GO film was studied using Raman microscopy, SEM, VSM and EDX. Raman microscopy approved existence of the GO film on the outward surface of the substrate by matching the prominent G, D, 2D and D” peaks in contrast to the previous research works. Furthermore, SEM micrographs and EDX elemental results, validated existence of the GO on the surface. In the end, it was observed that the electrophoretic GO sample magnetic properties excel at the sputtered permalloy sample to a great extent.
