DyMo/sub 6/S/sub 8/ and TbMo/sub 6/S/sub 8/ are superconducting below T/sub c/ = 2.05 K, and ErMo/sub 6/S/sub 8/ below T/sub c/ = 2.2 K. Neutron diffraction has been used to study the development of magnetic order in these materials at temperatures T/sub M/ less than T/sub c/. In zero applied magnetic field, the DyMo/sub 6/S/sub 8/ and TbMo/sub 6/S/sub 8/ order antiferromagnetically, the magnetic order coexisting with the superconductivity. The ErMo/sub 6/S/sub 8/ sample showed no long-range magnetic order when initially cooled down in zero applied magnetic field. After a magnetic field was applied and reduced to near zero, the sample showed coexistent antiferromagnetic order below T/sub M/ = 0.2 K. Magnetization measurements on DyMo/sub 6/S/sub 8/ and TbMo/sub 6/S/sub 8/ at temperatures below T/sub M/ suggest the development of ferromagnetic order as the applied field increases. In the case of TbMo/sub 6/S/sub 8/, the neutron data show ferromagnetic order developing for H> or =H/sub c/2 where H/sub c/2 is the upper critical field for superconductivity. For DyMo/sub 6/S/sub 8/ ferromagnetic order develops for H much less than H/sub c/2. Both ferromagnetic and antiferromagnetic order occur with the sample in the superconducting state.
