摘要：

We present an analytic derivation of the linear temperature dependence of the inverse static susceptibility chi(-1)(T,U)similar toT-T-c(U) near the transition from a paramagnetic-to-ferromagnetic correlated metal within the dynamical mean-field theory for the Hubbard model. The equations for the critical temperature and interaction strength of the transition are also determined.
