Superconductivity and ferromagnetism are usually antagonistic phenomenon; however in nanoscale heterostructures we may juxtapose the two effects to create exotic pairing mechanisms. One such state is created when a conventional superconductor (such as Nb) and a metallic ferromagnet (such as Co) are place in contact which results in an anti-parallel magnetisation being induced in the superconductor which decays with the normal superconducting coherence length (tens of nanometres). This effect is highly dependent on the ferromagnet/superconductor interface diffusion and increases in magnitude with increasingly diffuse interfaces. We propose to measure the magnetisation induced in the superconductor and how it is affected by the interface properties by artificially diffusing the interface (through co-sputtering or annealing) in a series of otherwise identical multilayers.
