Abstract
A neutron diffraction study on the superconducting Ru-1222 ruthenocuprate RuSr(2)Y(1.5)Ce(0.5)Cu(2)O(10-delta) (T(c)= 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)mu(B). 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 < 0.3 mu(B).
