We calculate the net magnetization for the a dimensional half-filled Hubbard model doped with one and multiple nonmagnetic impurities, using quantum Monte Carlo (QMC) method, to understand the suppression of antiferromagnetic order in strongly correlated electron systems such as La 2 CuO 4 by doping
## A set of parameters for the three-band Hubbard model is determlned by comparison of Quantum Monte C~lo results with experimental values for the charge transfer gap. With the obtained parameter set we have calculated the spectral function A(k,t~) for the one-particle Green's function. We find ve
