Abstract

Electrodeposition of NiFeCr thin ï¬lms have been successfully carried out from chloride bath at a constant current density (1 A/dm2) by varying the chloride bath concentration (0.1, 0.2, 0.3 and 0.4mol/lit). The surface morphology, microstructure and magnetic properties such as coercivity, saturation magnetization were investigated for electroplated NiFeCr thin ï¬lms. The SEM micrographs of the electrodeposited ï¬lms from the chloride bath concentration of 0.4 mol/lit have no micro cracks and also the ï¬lms have more uniform surface morphology as compared with the film coated from lower concentration. The predominant peaks in X-ray diffraction pattern reveal the crystalline nature of the ï¬lm and found to have BCC structure. From the VSM results of the electrodeposited NiFeCr thin ï¬lms, the various magnetic analysis such as coercivity, saturation magnetization were calculated. The hardness and adhesion of the electroplated ï¬lms with substrate were also investigated. Reasons for variation in magnetic properties and structural characteristics were discussed.
