Description
Aditya Singh and co-authors report thin films of a tungsten nitride that superconduct strongly under high magnetic fields, in a paper published in 2026. Metal nitrides are tough, hard, and often superconducting, but this exact compound had barely been studied for that trait. The films were grown with atoms arranged in a neat cubic pattern.
The material kept its superconductivity up to a field of about eight and a half tesla, which is unusually high for its family. Its switching temperature sits in the few-degree range typical of these nitrides. The authors argue the mix of strength, chemical stability, and field tolerance suits the compound for quantum devices and cold electronics. The work adds a fresh entry to the list of useful superconducting nitrides.
