摘要: Polycrystalline samples of (Ru0.9Nb0.1)Sr2(Gd1.34−xNdxCe0.66)Cu2Oz (x = 0 − 0.67) have been synthesized and characterized by X-ray diffraction (XRD), electrical resistivity, thermoelectric power magnetization measurements. Resistivity measurements revealed that the onset transition temperature (Tco) decreased slightly from Tco 40K for x to 22K 0.67. Magnetization showed partial substitution Gd Nd leads a significant decrease in magnetic ordering temperature. A suppression weak ferromagnetic component field-cooled (FC) with Nd-doping content was also observed ≥ 0.34. The changes superconducting temperature, FC are discussed conjunction change hole concentration local structural Ru sublattice induced doping, based on Rietveld refinements XRD data.
