摘要：

We investigate Meissner effect in normal metal/superconductor junctions where the interface is spin-active. We find that the orbital magnetic susceptibility of the normal metal depends on the temperature in an oscillatory fashion, accompanied by its sign change. Correspondingly, magnetic field and current density can spatially oscillate in the normal metal. These results stem from the generation of odd-frequency pairing due to the spin-active interface.
