Abstract
The authors develop superconducting high-entropy alloy films by means of magnetron sputtering. The superconducting parameters derived for all the films are found to be close to the parameters usually reported for amorphous superconductors. These results indicate that these films of high-entropy alloys are promising candidates for superconducting device fabrication
