Fig: Morphing of superconducting correlations f in a rotating magnetization h.
One of the characteristic features of a superconductor is that conduction electrons form a condensate where they bind into Cooper pairs. These electron pairs are in a well-defined singlet or triplet state that is determined by the interactions in the material. Cooper pairs can leak into a magnetic system placed in proximity to the superconductor. If the magnetic material is inhomogeneous (magnetic domains, multilayer, etc.) then the state of the Cooper pairs changes; singlet- triplet mixing occurs. We describe the metamorphosis of superconducting pair correlations in an inhomogeneous magnetic system and discuss how the cascading effect allows them to survive deep in the material. Several experiments are suggested in which these correlations can be probed.
