Cascading Proximity Effects in Rotating Magnetizations

Abstract

We demonstrate two effects that occur in all diffusive superconducting-magnetic heterostructures with rotating magnetization: the reappearance of singlet 0,0>|0,0> correlations deep in the magnetic material and a cascade of s=1s=1, m=0,±1m=0, \pm 1 components (in the two spin-1/21/2 basis s,m>|s,m>). We do so by examining the order parameter and Josephson current through a multilayer with five mutually perpendicular ferromagnets. The properties of the middle layer determine whether the current is due to m=0m=0 or m0m\neq 0 contributions. We conclude that so-called long- and short-range components are present across a proximity system with rotating magnetization.
