Experiments on a nearly spin degenerate two-dimensional electron system reveals unusual hysteretic and relaxational transport in the fractional quantum Hall effect (FQHE) regime. The magnetotransport near the transition between the spin-polarized and spin-unpolarized Image states is accompanied by a complicated series of hysteresis loops reminiscent of a classical ferromagnet. In conjunction with ...
