Samarium orthoferrite SmFeO3 thick films prepared by screen printing technique were surface modified with cobalt chloride. Surface modification was achieved by dipping technique. SmFeO3 thick films were dipped into 0.1 M aqueous solution of cobalt chloride for 5 min. After drying, the modified films were fired in Muffle furnace at 5500C for 30 min. SmFeO3 powder was analyzed by X-ray diffraction (XRD) and Fourier Transform Infrared spectroscopy techniques. The observations depict that powder sample is made up of SmFeO3 nanoparticles. As-fabricated pure and Co-surface modified SmFeO3 thick films were analyzed by Field Emission Scanning Electron Microscope (FE-SEM) to observe its microstructure. The FE-SEM results revealed the formation of nanocrystalline SmFeO3 grains and the porosity of films. For the conformation of Co deposition, the Energy-dispersive X-ray (EDAX) analysis of the Co modified SmFeO3 thick film was carried out. The EDAX analysis showed that Co was successfully deposited on pure SmFeO3 surface with no additional impurities. The effect of Co modification on the surface morphology of pure SmFeO3 thick film was discussed.
