Certification of YBa2Cu3O7−x Single Crystals
A method for evaluation of the critical temperature T c and the width of the superconducting transition Δ T c in HTSC single crystals has been developed. By this method, the first derivative of the temperature dependence of the resistivity, , is constructed. A technique for synthesis of YBa 2 Cu 3 O...
