Abstract
We study the spin-Peierls states in the presence of spin defects for CuGeO3 where magnetic ions Cu2+ are replaced by non-magnetic ones Zn2+. Based on the action for the bosonized Hamiltonian, we investigate the spatial dependence of the phase which expresses the spin fluctuation. Further, we calculate temperature dependence of the magnetic susceptibility by taking account of the spatial variation of the phase.
