Ea. Kafadaryan et Aa. Bush, FAR-INFRARED REFLECTIVITY STUDY OF VIBRATIONAL STRUCTURE IN SUPERCONDUCTING BI2SR2CACU2O8+X, Journal of physics. Condensed matter, 9(14), 1997, pp. 3071-3074
We report the anomalous temperature behaviour of phonons in the superc
onducting a-axis-oriented Bi2Sr2CaCu2O8+x texture detected by far-infr
ared reflectivity spectroscopy.
