In this work, we theoretically investigate the emergence of equilibrium spin currents (ESCs) in two-dimensional AM heterostructures using a tight-binding lattice model. We first study an AM-normal metal-AM (AM-NM-AM) junction and demonstrate that the $\\sigma_y$-polarized ESC exhibits a characteristic Josephson-like behavior, fundamentally governed by the relative angle ($\\theta$) between the N\\'eel vectors of the two AMs pointing in $xz$-plane.
