Reflectivity and Raman Spectra of Suyperconducting and Nonsuperconducting YBa2Cu3O7-δ Crystals
Abstract
Preparation and optical studies of essentially singledomain and twinned (in the a-b plane) YBa2Cu3O7-03B4; crystals are reported. Two types of anisotropy of reflection in the a-b plane have been observed; the first is attributable to the crystal symmetry, the other is governed by symmetry of twins. The experimental evidence for the effect of microtwinning on Raman spectra has been obtained.
