摘要：

The results of magnetization measurements on the S = 1 linear-chain Heisenberg antiferromagnet Ni(C2H8N2)2NO2(ClO4) containing Cu2+ impurities are reported. The magnetization obtained at low fields is quantitatively explained by the model that the valence bonds are broken at the Cu2+ sites resulting in the spin 1/2 states at the Ni2+ sites neighboring the impurity. The behavior of the magnetization at the high fields is also discussed.
