Both Dy/sub 1.2/Mo/sub 6/S/sub 8/ and Tb/sub 1.2/Mo/sub 6/S/sub 8/ are superconducting below T/sub c/=2.05 K. Neutron scattering studies show that these compounds in zero applied magnetic field develop long-range antiferromagnetic order (greater than 300 A) at T/sub M/=0.4 K and T/sub M/=1.0 K, respectively, which does not destroy the superconducting state. Magnetization measurements at temperatures below T/sub M/ suggest the development of ferromagnetic order as the applied magnetic field increases. In the case of Tb/sub 1.2/Mo/sub 6/S/sub 8/ the neutron data show long-range ferromagnetic order developing for H> or =H/sub c2/=1.9 kOe where H/sub c2/ is the upper critical field for superconductivity. However, for Dy/sub 1.2/Mo/sub 6/S/sub 8/ long-range ferromagnetic order begins to develop at H=200 Oe, a field much less than H/sub c2/=1.2 kOe. As the ferromagnetic intensity increases, the antiferromagnetic intensity decreases. Between H=200 Oe and H=1.2 kOe both ferromagnetic and antiferromagnetic order occur with the sample in the superconducting state.
