Colour evolution of the oxide layer formed on the Au-25Fe AND Au-24.5Fe-0.5Co

The colour theory proposed by Heavens in 1991 has been applied to calculate the thickness of magnetite thin layers, Fe3 O4 , which were obtained by heat treatment at 250 °C in a gold alloy (Au-24.5Fe-0.5Co). The reflectance spectra obtained from the polished samples with different oxidation (and co...
