Effect of Co layer thickness on structural and magnetic properties of Fe50Co50 films
The granular Co(x nm)/Fe50Co50 films have been prepared by magnetron sputtering onto glass substrates at room temperature and the Co thickness were different from 0nm to 13nm. It has been found that the structure and magnetic properties of the Co/Fe50Co50 films depend strongly on the Co layer thickness. Vibrating sample magnetometer measurements indicate that the in-plane coercivity reaches minimum in 1.3nm Co thickness. Simultaneously, remnant magnetization reaches a lower value. Scanning probe microscope was used to scan surface morphology and magnetic domain structures. The values of the surface roughness were lower than others in 1.3nm Co thickness.
