In the course of a neutron diffraction study of single crystals of Cr grown by the strain-anneal method it was observed that the antiferromagnetic superstructure reflections exhibited characteristic splittings. An analysis of these splittings led to an interpretation in terms of an antiphase antifcrromagnetic domain structure. From the experimental observations, the intensity distribution in reciprocal space was deduced. From the integrated intensities of the magnetic superstructure peaks (100), (111), and (210), the Bohr magneton number was found to be 0.4 cores consistin 0.05. (W.D.M.)
