摘要

Our detailed measurements show the undoped double perovskite Ba ²⁺₂Pr³⁺Ru⁵⁺O^2- ₆ to be a nonmetallic (insulating) spin glass (SG) and the ∼5-10% Cu-doped (i.e., Cu-concentration/(Cu+Ru-concentration) ∼5-10%) system to be a spin glass superconductor (SGSC), though the critical temperature, T_c, (∼8-11 K) and the superconducting volume fraction, f_sc, (∼1-4%) are small. This smallness is presumably due to the presence of a large number of pair breaking spins and small carrier concentration in the lattice. Results and their implications are discussed.
