Shining lasers at superconductors can make them work at higher temperatures, suggests new findings from an international team of scientists including the University of Bath. Superconductors conduct electricity without power loss and produce strong magnetic fields, used in medical scanners, super-fast electronic circuits and in Maglev trains with superconducting magnets to allow train levitation over tracks, eliminating friction.
Currently superconductors only work at very low temperatures, requiring liquid nitrogen or helium to maintain their temperature...
