Abstract

A neutron diffraction study on the superconducting Ru-1222 ruthenocuprate RuSr2Y1.5Ce0.5Cu2O10-d (Tc=35 K) prepared by the high-pressure high-temperature technique reveals long-range antiferromagnetic order below 140 K. Neighboring spins are antiparallel on the ab plane but both antiferromagnetic and ferromagnetic alignments along c are observed. The refined low-temperature moment is 1.5(3)µB. The observation of a ferromagnetic moment from magnetic measurements suggests that the Ru spins are canted below 91 K with a zero-field moment of <0.3µB.
