A rich variety of physical effects in the spin dynamics arises at the interface (domain wall) between different magnetic materials. Engineered physical systems based on magnetic interlaced structures have received wide interest in the last years as a starting point to implement spin transistors, memories and other spintronic devices. In this work, we use a coherently-coupled mixture of ultracold bosonic gases to realize analogues of magnetic junctions. The spatial inhomogeneity of the atomic…
