Abstract: We report on the experimental characterization of a spatially extended Josephson junction realized with a coherently coupled two-spin-component Bose-Einstein condensate. The cloud is trapped in an elongated potential such that transverse spin excitations are frozen. We extract the nonlinear parameter with three different
manipulation protocols. The outcomes are all consistent with a simple local density approximation of the spin hydrodynamics, i.e., of the so-called Bose-Josephson junction equations. We also identify a method to produce states with a well-defined uniform magnetization.
