Influence of Magnetic Order on Proximity-Induced Superconductivity in Mn Layers on Nb(110) from First Principles

Bal\'azs \'Ujfalussy, Kyungwha Park, Sohair ElMeligy

Antiferromagnetic order in Mn layers on Nb(110) induces an order of magnitude more singlet superconductivity than ferromagnetic order.

Claims

C1strongest claim

We also find an order of magnitude difference in the induced singlet part of the SC order parameter in the Mn layer/s between the FM and AFM cases in favor of the AFM pairing with the maximum still being only 4.44% of the bulk Nb singlet order parameter value.

C2weakest assumption

The assumption that the chosen ferromagnetic and antiferromagnetic configurations are the stable ground states and that the screened KKR plus BdG solver captures the proximity effect without significant errors from the local-density approximation or from the treatment of the interface potential.

C3one line summary

First-principles BdG calculations show antiferromagnetic order in Mn layers on Nb(110) induces an order-of-magnitude larger singlet superconducting order parameter than ferromagnetic order, reaching at most 4.44% of bulk Nb value, with magnetic-order-dependent secondary gaps and V-shaped in-gap DOS.
