Maximum value of magnetization of the system

  1. Maximal value of magnetization of the system of ##N## atomic moments is
    ##M_s=Ng\mu_B J##
    How this result is obtained? Some reference maybe?

    In the case of localized feromagnetism in the mean-field approximation
    ##H=-\frac{J}{2}zN\vec{S}\cdot \langle \vec{S} \rangle \vec{S} \rangle##
    and then in book Physics of magnetism and magnetic materials author uses
    ## \vec{S}=(g-1)\vec{J}##
    What is a logic behind that?
