Magnetization process for an S/F/S Josephson junction with a position (x) and magnetic field (H) dependent magnetic susceptibility χ(x, H) and magnetization M(x, H). (a) For H = 0 the net barrier moment is zero everywhere but on increasing H (b–d), M increases faster at the junction edges and propagates inwards until the barrier moment saturates (H = Hs) (d). (e) Spatial variation of magnetic induction B and superconducting phase difference ϕ for 0 < H < Hs. The external field H is applied in the y direction. The variables (M, ϕ, H, B) are plotted on the z-axisand labelled.
