Superconductors are often described as a possible foundation for the next generation of ultra-efficient technology. In theory, they could move electricity without wasting energy as heat. In practice, they are still difficult to use outside the lab.
A team at Chalmers University of Technology in Sweden now reports a new way to improve that outlook by designing a material that supports superconductivity at higher temperatures while also standing up to strong magnetic fields. If the approach can be extended, it could help advance low-power electronics, quantum devices, and other technologies where energy losses matter.
