Maximal value of magnetization of the system of ##N## atomic moments is(adsbygoogle = window.adsbygoogle || []).push({});

##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?
