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