Abstract
A systematic study of structure and superconductivity of (RE)Ba2Cu3Ox (RE: rare earch) is carried out. All superconducting (RE)Ba2Cu3Ox have oxygen deficient perovskite structure. As the ion radius of the RE ion increases, lattice parameters increase and the orthorhombic distortion becomes smaller. Superconducting transition temperature is lower for (RE)Ba2Cu3Ox with smaller RE ion radius. Upper critical fields (Hc2) are measured resistively up to 90 kOe. All superconducting (RE)Ba2Cu3Ox have similar values of dHc2/dT|Tc to that of YBa2Cu3Ox. The estimated Hc2 at absolute zero ranges from 1250 kOe to 1850 kOe.Keywords
