Mössbauer spectra of a single crystal of LuFeCoO4 are studied in the temperature range between 4.2 K and 70 K. The Mössbauer spectra are separated into two components. We propose a model that one of three spins in a spin plane is parallel to the c-axis and other two orient to 120° to the c-axis. This model explains the experimental data satisfactory. It is concluded that the spins parallel to the c-axis are more stable than the other when temperature is increased. The Ising like character observed in susceptibility measurements can be explained by this spin arrangement in the spin planes.
