Abstract

FeCoNi(CuAl)0.2 high entropy alloy (HEA) thin films were produced by magnetron sputtering. Results from X-ray diffractometry analysis, scanning electron microscopy, energy dispersive spectroscopy, and atomic force microscope indicate the formation of a single face-centered cubic solid solution with a homogenous distribution of alloying elements in the film according to the designed composition after 30 min of sputtering. The vibrant sample magnetometer test illustrated soft magnetic behavior with 139.67 emu/g magnetic saturation (MS) and 7.96 Oe coercivity field (Hc) in a 2 T applied magnetic field with excellent hardness 136.8 GPa and Young’s modulus 7.33 GPa. The formation of micro-nano columnar crystals led to a higher MS and lower Hc.
