We study electron-nuclear spin coupled systems implemented in microscopic fractional quantum Hall (FQH) devices. We find that the longtitudinal resistance in such systems oscillates with a period of about ∼200 s and is driven by a constant voltage instead of a constant current. This anomalous behavior suggests that an average nuclear spin polarization self-sustainingly oscillates between randomized and polarized states which reveal the nonlinear nature of the mesoscopic electron-nuclear spin coupled systems.
