We present new analytical and numerical results of the dynamics of reversed field current layers in the Hall limit (i.e., characteristic length scales smaller than the ion inertial length). A rapid, localized thinning of the current layer leads to the generation of a nonlinear, shocklike structure that propagates in the B x inverted Delta(n) direction. This magnetic structure is self-supportive and can lead to a nonlocal thinning of the current layer and the release of magnetic energy.
