N2 - Local magnetic moments around a nonmagnetic impurity in the two-dimensional (formula presented) model are studied within Gutzwiller approximations and the Bogoliubov–de Gennes theory. We show that the resonance peak in the local density of states expected around the impurity splits into two when local magnetic moments are induced near the impurity. Therefore, in the recent scanning tunneling spectroscopy data on (formula presented) [Pan et al., Nature (London) 403, 746 (2000)] which show the sharp resonance peak, there is no evidence of the existence of local moments around the Zn impurities. It is shown that the absence of local moments is caused by the tendency of electrons to avoid the impurity.
