The effect of substitution of Si to Ge in CuGe1−xSixO3 single crystals has been studied by magnetic susceptibility, Cu nuclear magnetic resonance, and neutron scattering measurements. The phase diagram in the (x,T)-plane is characterized by an initial rapid decrease of the spin-Peierls temperature, TSP, on increasing x and by the occurrence of a three-dimensional long range ordered antiferromagnetic phase at T=TN in the range 0.005≤x≤0.05. This phase diagram is qualitatively discussed. The neutron scattering data for x=0.007 show that the dimerization which takes place below TSP is not suppressed below TN. © 1996 American Institute of Physics.
