| Summary: | Bulk magnetic and neutron diffraction studies have been carried out to determine the magnetic properties of
Ba
2 (
UCu)
O
6 at low temperatures. In the frame of pseudo-perovskite unit cell, the magnetic ordering of the Cu moments at 1.5 K can be described by the propagation vector
k = {0, 0, 0}
, corresponding to the G(+-+-) or equivalent A{+--+} configuration with the moment alignment close to the [110] direction. As concluded from both neutron diffraction and susceptibility data,
Ba
2(
UCu)
O
6 exhibits quasi-two-dimensional antiferromagnetic properties, resulting from a weak interaction between antiferromagnetically coupled Cu layers. The magnetic moment of
Cu
2+
ion amounts to (0.86±0.23)
