Neutron-diffraction study of the magnetic superconductors Dy(Ru/sub x/Rh/sub 1-x/)/sub 4/B/sub 4/
Powder neutron-diffraction measurements have been performed for several concentrations on the system Dy(Ru/sub x/Rh/sub 1-x/)/sub 4/B/sub 4/, which displays varied and interesting types of magnetic and superconducting behavior. For the concentration x = 0.15, acollinear antiferromagnetic order with a peculiar temperature dependence of order parameters, including pronounced thermal hysteresis, coexists with the superconducting state. The nonsuperconducting x = 1.00 compound also develops long-range magnetic order, but with a ferromagnetic as well as an antiferromagnetic component. The diffraction pattern corresponding to a concentration x = 0.60, however, shows no long-range magnetic order for T>0.3 K, but rather the development of a broad peak suggesting the onset of some short-range magnetic correlation.
