The formation of high entropy alloys (HEAs) has the potential to influence solid solution phase stability through control of configurational entropy. For new materials with attractive properties for mechanical, magnetic, electronic and photonic applications, the oxidation behaviour and resistance is an important property (as well as interesting for synthesizing new structures). Here we have synthesized thin films of CrFeCoNiCu films of different thickness by sputtering onto insulating and optical transparent substrates in order to measure electrical and optical properties. The deposition was done by reactive DC magnetron sputtering from a sputtering targets made from an equimolar alloy of the elements. All the samples were characterized by structural and electrical optical methods. The as deposited films had fcc structure and also showed interesting electric and magneto resistive properties. The samples were annealing in air and O2 ambient in the temperature range of 300 to 500 °C forming an oxide layer.
