摘要：

The Wigner-liquid model developed recently in strongly correlated low carrier density systems with 4f-electrons was applied to the high-T(c) CuO2 layer systems. It is expected that pair formation of up- and down-spin holes inducing magnetic polarons occurs through Coulomb interaction as well as enhancing the exchange energy pin and the superconductivity occurs as Bose condensation. Temperature and the hole concentration dependences of the spin-spin correlation length are explained very well by this model.
