摘要：
It is shown that a single impurity can produce a pair of bound states inside the gap of thes-wave van Hove superconductor. Both nonmagnetic and magnetic states have been considered using the Anderson Hamiltonian. The results are discussed relative to the case of the classical spin in thes-wave van Hove superconductor.
