摘要
This letter deals with the suppressive effect of the nonmagnetic impurity,doped into the parent compound of the high-T_(c) superconductor,on the spin density wave(SDW)state.Taking into account the van Hove singularity in the Fermi surface of the two-dimensional square lattice,our results indicate that the nonmagnetic impurity can lead to sharp reduction of the SDW order,which is in qualitative agreement with the experimental reports.
