摘要：

A model is proposed for the observed heavy-fermion like behavior of electron doped Nd2CuO4. It differs from the traditional description of heavy fermions because of the strong correlations between the conduction electrons. The effects of these correlations are simulated by breaking the spin symmetry. It is shown that the model can qualitatively account for the observed effects.
