Spectral features induced by 45° in-plane misoriented grains have been observed in the far-infrared magnetotransmission of (Formula presented)(Formula presented)(Formula presented) thin films. Two strong dispersive features are found at 80 and 160 (Formula presented) and a weaker one at 116 (Formula presented). 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.
