✦ Synopsis

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 T. Hsu [Physica C 213 (1993) 305] which successfully describes these experiments we identify the resonance as a hybridized cyclotron-pinning resonance.

A study of flux pinning has been performed using an oscillator consisting of a bar of sintered YBa2Cu307~ ceramic, clamped at both ends, which was made to perform flexural vibrations in a transversely applied magnetic field. Vibrations were driven by an alternating current flowing along the bar. The
