Fig. 3: Pair amplitude decay in WNL Josephson junctions compared with NM and HM junctions.

Evolution of the absolute value of equal-spin (↑↑ and ↓↓), mixed-spin (↑↓ + ↓↑) triplet, and spin-singlet (↑↓ − ↓↑) pair amplitudes into the middle of the WNL within the (a, b) minimal model Eq. (1) with chemical potential set to μw = 0, 0.1, respectively, and c generic model Eq. (2) with μw = 0. It is compared with similar junctions with NM (d) and HM without (e) and with (f) an spin-active interface. Pair amplitudes are extracted for ω = 0.5Δ. Same parameters as in Fig. 2 for the WNL, while the NM and HM are the spin-independent part of the WNL with the HM having an additional mzσz with mz = 0.5 magnetization in the bulk and an interface mxσz with mx = 1 term modeling the spin-active interface.
