摘要

Coexistence of superconductivity and magnetic ordering or their mutually exclusive existence in solids is one of the fundamental problems of solid state physics. To determine the effect of Pr substitution for Gd on electrical and magnetic properties of RuGd_(1.5)Ce_(0.5)Sr_2Cu_2O_(10-delta) (Ru-1222), the Ru(Gd_(1.5-x)Pr_x)Ce_(0.5)Sr_2Cu_2O_(10-delta) samples with x=0.0, 0.01, 0.03, 0.035, 0.04, 0.05, 0.06, 0.1 have been prepared by the standard solid-state reaction technique. The XRD patterns for various x have been obtained to show their phase purity. The resistivity and magnetoresistivity of samples have been measured at various temperatures and different magnetic fields up to 1.5T.
