Abstract：
In this paper, we calculate the properties of the spin polarized isospin asymmetric nuclear matter by employing the Skyrme effective interaction with two sets of parameters SKM * and SⅢ, giving the equation of the state and the radio det(1/χ)det(1/χ_F) which is shown as a function of the density for several values of the asymmetry parameter β. It is shown within the Skyrme-Hartree-Fock framework that there is the ferromagnetic phase transition in the isospin asymmetric nuclear matter at some density, above which the nuclear matter becomes stable against spin fluctuation, and the critical density for the ferromagnetic transition decreases with increasing the asymmetry parameter. In addition, we also compare the phenomenological Skyrme model with microcosmic BHF (Brueckner-Hartree-Fock) theory with respect to the phase transition.
