The role of canting in superconducting-spin valve structures*

Superconducting spintronic devices have become a popular conceptual alternative to classical computing, although the development of these technologies is in the early stages. Common designs revolve around various magnetic configurations that compose the interlayer in a Josephson junction. We study the dependence of canting on the Josephson current in a magnetic structure with symmetric and anti-symmetric configurations of trilayers and pentalayers. Fully numerical calculations are justified by a toy model. The two structures are chosen because they display opposite behavior under canting. We analyze the components of the Gor'kov function and how they affect the 0-π transition. A recent classification according to the symmetry of the paired states is used to analyze the results. We also propose a novel feature that is experimentally observable and arises from the interplay of singlet and triplet correlations.
