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 Fe Se grownThe 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.
