Interaction between superconductivity and magnetism in iron-lead thin films

DOI

A previous CRISP measurement allows us to show for the first time using PNR a change in the response due to superconductivity in an Fe/Pb/Fe tri-layer sample. This type of system is of particular interest owing to the possibility of novel forms of superconductivity appearing on mesoscopic length scales. One manifestation of this could be a so-called ¿inverse-proximity¿ effect, in which a magnetisation is induced in the superconducting layer by coupling to the ferromagnetic layers. With more detailed measurements, particularly of the field dependence, we hope to distinguish this effect from Meisner screening. In addition, a low-energy muon study found evidence for a spin-density wave state, with a particular modification of the magnetisation in the Pb layer near the interfaces below TC. Observing this with PNR would contribute significantly to a fuller understanding of the effect.
