Abstract / Description:CuSb2O6 crystallizes with a monoclinically distorted variant of the
trirutile structure type with Cu2+ ions arranged in square planar nets
being structurally well separated from each other by Sb-O building
blocks. Using elastic neutron diffraction we have established the
low-temperature nuclear structure and antiferromagnetic (afm)
arrangement of Cu moments at 2 K. The magnetic unit cell is doubled
with respect to the nuclear cell along the a- and c-axes. The magnetic
anisotropy in the ordered state suggests that Cu moments of magnitude
0.51(2) mu(B) lie in the a-b plane. (C) 2004 Elsevier B.V. All rights
