We introduce a novel FeMnCoCrAl high entropy alloy (HEA) synthesized by high throughput combinatorial sputtering. The thin film library, exhibiting multiple concentration gradient, was screened over a wide non-equiatomic (Al = 3.5-55 at.%) composition, and HEAs stabilizing as i) multi-phase, ii) single random BCC and iii) ordered BCC phases were identified. The elemental distribution across different phases was investigated by atom probe tomography (APT). A well-defined relationship between the stabilized phase and the measured soft magnetic properties viz. saturation magnetization, Curie temperature and electrical resistivity was observed in the HEA system. The seen phase formation based magnetic behavior dependence in the thin film HEA, was validated by experimentation on the bulk HEA and ab-initio based density functional theory calculations.
