Abstract
Spectral features induced by 45° in-plane misoriented grains have been observed in the far-infrared magnetotransmission of YBa2Cu3O7−δ thin films. Two strong dispersive features are found at 80 and 160 cm−1 and a weaker one at 116 cm−1. The data can be well represented by Lorentzian oscillator contributions to the conductivity. Several possible interpretations are discussed. We conclude that the resonances are due to vortex core excitations. © 1996 The American Physical Society.
