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 meanfield 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}=(g1)\vec{J}## What is a logic behind that?
