Nano crystalline Ni-Co-S alloy thin films were deposited on the copper substrate at different temperature by electrodeposition method. Electro deposited Ni-Co-S thin films were subjected to the structural, mechanical and magnetic characterization analysis. The chemical composition of the coated films was analysed by EDAX. The surface and structural morphology of the coated film were analyzed by using SEM and XRD. The mechanical properties of NiCoS films have been studied by VHT. The magnetic properties of thin films have been analysed by VSM. The electroplated NiCoS thin films were strongly adherent to the copper substrate The SEM pictures of NiCoS thin films show that, the deposits of thin films are crack free, uniform and bright surface with fine grain size. All the electro deposited Ni-Co-S films exhibit FCC crystalline structure with crystalline size in the order of nano scale. The VSM result of NiCoS thin films shows that the NiCoS thin films coated at high bath temperature have highest saturation magnetisation value with lower coercivity. Due to highest magnetisation value with low coercivity, NiCoS thin films can be used for the manufacturing of MEMS and NEMS devices. © 2015, Sphinx Knowledge House. All rights reserved.
