We demonstrate two effects that occur in all diffusive superconducting-magnetic heterostructures with rotating magnetization: the reappearance of singlet |0, 0⟩ correlations deep in the magnetic material and a cascade of s = 1, m = 0,±1 components (in the two spin-1/2 basis |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 = 0 or m ≠ 0 contributions. We conclude that so-called long- and short-range components are present across a proximity system with rotating magnetization.
