抄録

Magnetization and ESR measurements have been performed on Si-doped CuGe1-ySiyO3 (y = 0.01 and 0.02) single crystals. The y = 0.01 sample shows a spin-Peierls transition at TsP = 11 K as well as undoped material and additionally show an antiferromagnetic state below TN = 2.8 K. When an external field is applied to the c-axis below TN, two magnetization jumps due to the spin-flop and the transition from dimerized spin-Peierls phase to magnetic phase are observed at 0.98 T and 11.5 T, respectively, which means the coexistence of spin-Peierls and antiferromagnetic states. On the other hand, the y = 0.02 sample shows only an antiferromagnetic transition at TN = 4.8 K.
