A resonance has been observed in the mixed state of YBaeCu30 7 thin films at h o) ~ 3 meV in the (hole) cyclotron resonance active mode of circular polarization. This chiral response is inconsistent with the conventional models of vortex dynamics. Based on a clean-limit theory recently developed by
Nonlinear current-voltage characteristics have been measured for ultrathin (16-400/~) YBa2Cu3Or\_6 films in high magnetic fields. A scaling analysis of these data reveals deviations from the universal vortex-glass critical scaling behavior observed for thick films. This is argued to be a dimensional
