Crystal structure of the ferromagnetic superconductor RuSr2(Gd1.3Ce0.7)Cu2O10 –  by powder neutron diffraction

Christopher S. Knee, Brian D. Rainford and Mark T. Weller


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