Abstract: Amorphous Ni-Fe-Co-Mn-Bi-Tm high entropy alloy films were firstly prepared by potentiostatic electrodeposition. The results indicate that the six elements can be co-deposited in an organic system of DMF (N,N-dimethylformamide)-CH3CN. The surface of the film is composed of compact and uniform particles with triangular cone shape and a particle size of 100—200 nm. A simple face-centered-cubic structure is identified by XRD patterns after the films were annealed under Ar atmosphere. The annealed alloy film shows soft magnetic properties and the magnetization decreases with Fe content decreasing.
