Abstract

The 1222-type ferromagnetic, superconducting cuprate, RuSr2((Gd1.3Ce0.7)-Gd-160)Cu2O10-delta, contains RuO6 octahedra that are rotated 13.4 degrees around the c-axis and tilted reducing the Cu-O(1)-Ru angle to 168.2 degrees at 295 epsilonK. The oxygen deficiency delta has been determined as 0.22, indicating a hole doping mechanism, similar to that proposed for GdSr2RuCu2O8, facilitates superconductivity
