We measured differential optical reflectivity (DOR) of YBCO single domains. DOR measurements reject the temperature independent bulk reflectivity and reveal dR dT. These measurements detect the superconducting transition, and reveal specific anisotropy associated with high-Tc superconductivity. © 1995.
