Abstract

The nano crystalline NiFeCr thin films were synthesised on the surface of aluminium substrate at different bath temperature like 30, 40, 50 and 60°C by applying a constant current density of 0.5 A/dm2. All the coated NiFeCr thin films were subjected to the structural, mechanical and magnetic characterization analysis (EDAX, SEM, XRD, VHT and VSM). The SEM pictures of NiFeCr thin films shows that, the film have crack free, uniform and bright surface morphology with fine grain size. The XRD pattern reveals the BCC structure of NiFeCr thin films with three predominant diffraction peaks. The VSM data of NiFeCr clearly shows their magnetic nature. The NiFeCr thin films coated at high bath temperature have highest saturation magnetisation value with lower coercivity. Because of its low coercivity with highest magnetisation value, the NiFeCr thin films may used for the manufacturing of MEMS devices..
