摘要

The Meissner effect is the expulsion of a magnetic field from a superconductor and thus can be used to judge whether a material is a superconductor or not.Now,Zhang et al.[1] report the observation of Meissner effect with an onset temperature at 65 K in the monolayer FeSe grown on Nb-doped SrTiO3 (STO) substrate,clearly demonstrating it is an interface-enhanced high-Tc superconductor.
