摘要：

The magnetic susceptibilities of polycrystalline Cu1-xZnxGeO3 were measured to study the effects of nonmagnetic impurities on the spin-Peierls transition. The transition temperature drastically reduces upon Zn doping and the spin-Peierls state collapses around x = 0.03. The Zn doping causes another phase transition in the samples with 0.02 less-than-or-equal-to x less-than-or-equal-to 0.08, which proved to be spin-glass-like. The present Letter provides the first study of the spin-Peierls system with impurities.
