| Abstract: | The effect of spin polarization on the ground state of Kondo type system is a fundamental issue in study of Anderson model. By using variational and diagonal methods we analysis the stability of Kondo singlet state in s-d model and Zhang-Rice singlet state in two-component model for high Tc superconductivity when Cu site spin polarization is considered. |

| Keywords: | Anderson model spin polarization Zhang-Rice singlet high temperature superconductivity |
