Abstract
Abstract The superconducting and normal state properties of the pseudoquaternary system Y1−xCdxBa2Cu3O7−δ with 0⩽x⩽1.0 were investigated by means of the AC electrical resistance, DC magnetization and powder X-ray diffraction measurements. For Cd concentration x⩽0.6, X-ray diffraction pattern reveals that the majority phase of the samples is of the oxygen deficiency perovskite type with a gradual change from orthorhombic to tetragonal structure as x increases. The superconducting transition temperature Tc was observed to remain almost unchanged up to x⋍0.6. This means the superconductivity occurs in orthorhombic structure as well as in the tetragonal structure. However, DC magnetization measurements taken at H=20 G indicate that the superconducting volume fraction in the sample decreases as x increases, although Tc remains unchanged, which shows that superconductivity in these samples is of granular characteristic.
