Effects of Heat Treatment on Structural, Optical and Magnetic Properties of Electro Deposited Fe-Ni-P Thin Films

Nanocrystalline Fe-Ni-P thin films have been prepared by electrodeposition method for different temperature. The structural, morphological, mechanical and magnetic properties are analyzed by different measurements. The structural and surface morphology of thin film were investigated by X-ray diffraction (XRD) and scanning electron microscope (SEM). XRD results showed all the electro deposited Fe-Ni-P films exhibits nanocrystalline FCC structure. The SEM pictures of Fe-Ni-P thin films show that the deposits of thin films are crack free, uniform and bright surface. The mechanical properties of Fe-Ni-P thin films have been analyzed by VHT. The electroplated Fe-Ni-P thin films were strongly adherent to the copper substrate. The VHT result of Fe-Ni-P thin films shows that thin film coated at high bath temperature has highest hardness value. Also VSM result shows that thin film coated at high bath temperature has higher magnetization value. This shows that the soft magnetic properties of Fe-Ni-P thin films are greatly enhanced by various temperatures.
