摘要: A new scenario is proposed for a class of disordered interacting electronic systems undergoing metal-insulator transition. The applies in the absence spin-flip mechanisms to that are not nearly ferromagnetic. At phase transition both spin susceptibility and coefficient linear term specific heat diverge with identical exponents, electrical conductivity vanishes continuously different exponent. Approximate values given critical exponents transport thermodynamic properties three-dimensional systems.
