Abstract
Neutron diffraction measurements have been performed on a LuFe2O4 single crystal with a hexagonal layered structure. At low temperatures a 2:l ferrimagntic spin arrangement of Fe ions is realized in each layer consisting of two triangular nets. The magnetic interaction between the different layers is so weak that the magnetic order is quasi-two-dimensional.
