Description

Hao Xu and a large team report a 2026 physics study of FeTe, an iron-based material whose bulk form orders magnetically instead of superconducting. Grown as thin films, though, it can carry current without resistance. Earlier routes to that state relied on oxygen or interface effects that muddied the mechanism.

The team grew clean FeTe films on a strontium titanate base and varied the amount of extra iron sitting between layers. Removing that surplus iron suppressed the magnetic order, sharpened the electronic behavior, and switched on superconductivity above 10 kelvin. Careful reheating restored the iron and reversed the change. Calculations pointed to a fluctuating magnetic ground state under the film's strain. The authors say precise composition is the real key.
