			Interplay of different orders in mesoscopic magnetic structures near superconducting interfaces can induce rich phenomena ranging from the proximity effect to the topological superconductor. In this talk, we focus on Josephson junctions consisting of two s-wave paired superconductors that interrupted by a ferromagnetic thin layer. In contrast to the usual Josephson junctions where the quasi-particle mainly tunnels through the quasi-1D transport channel, in a 2D junction where the transverse motion of the quasi-particle along the junction interface becomes important, we found a parameter-induced flat-dispersion in subgap modes due to a competition of the proximity effect and the ferromagnetic spin-splitting. This flat quasi-particle dispersion can be utilized for wavefunction switching for multi-domain structures thus opens up potential applications in spintronics.
