Abstract
A resonance has been observed in the mixed state of YBa2Cu3O7 thin fil ms at <(h$)over bar> omega congruent to 3 meV in the (hole) cyclotron resonance active mode of circular polarization. This chiral response i s inconsistent with the conventional models of vortex dynamics. Based on a clean-limit theory recently developed by T. Hsu [Physica C 213 (1 993) 305] which successfully describes these experiments we identify t he resonance as a hybridized cyclotron-pinning resonance.
