We have observed hysteretic behavior associated with spin transitions in the fractional quantum Hall effect (FQHE). Dramatic hysteresis in up and down sweeps of the magnetic field occurs in the vicinity of the spin-polarized to spin-unpolarized transitions in even-numerator FQHE states. The hysteresis is most pronounced at the lowest temperatures and disappears as the temperature is raised. These ...
