Probing possible p-wave superconductivity in Bi/Ni bilayers

DOI

Superconductivity and ferromagnetism are perhaps the best examples of how quantum mechanics can be employed to explain macroscopic phenomena. The two states, both containing coherent electrons, are traditionally considered antagonistic. Placing a ferromagnet in contact with a superconductor causes a suppression of the superconductivity. It is therefore a highly surprising result that placing very thin films of otherwise non-superconducting Bi next to ferromagnetic Ni, such that the two metals share an interface, causes the resulting heterostructure to superconduct with a critical temperature of about 4 K. It is possible that the superconducting mechanism responsible is the rare p-wave type. We plan to further investigate this highly unusual system using neutron reflectometry to extract the key length scales involved and probe the nature of the superconducting state.
