Abstract Neutron powder patterns of the hexagonal compound Mn<sub>0.2</sub>Cr<sub>0.8</sub>Sb, in which magnetization measurements indicate an antiferroniagnetic- ferromagnctic phase change, show that within the antiferromagnetic region the spin structure is similar to that of CrSb. Below the ferromagnetic Curie point weak supersturcture lines appear, with the relative intensities of the remainder of the neutron pattern changing only slightly. Additional measurements on the compound MnSb indicate that the spin structure is ferromagnetic with the moments directed along the hexagonal c axis. The results are discussed in relation to the types of exchange interactions present in these materials.
