The transition into a commensurate, collinear antiferromagnetic ground state with $\\mathbf{k}=(0.5, 0.5, 0)$ was found to occur below $T_\\mathrm{N}=22$ K. Above this temperature, the transition is preceded by the formation of a coexisting, short-range ordered, incommensurate state below $T_\\mathrm{{IC}}=45$ K whose two dimensional propagation vector evolves toward $\\mathbf{k}=(0.5, 0.5)$ as the temperature approaches $T_{\\mathrm{N}}$.
