It is possible to show that the mean magnetization is given by (for temperature below T_C ) \begin{equation*} \langle {\cal M}(T) \rangle \sim \left(T-T_C\right)^{\beta}, \end{equation*} where \beta=1/8 is a so-called critical exponent. A similar relation applies to the heat capacity \begin{equation*} C_V(T) \sim \left|T_C-T\right|^{-\alpha}, \end{equation*} and the susceptibility \begin{equation*} \chi(T) \sim \left|T_C-T\right|^{-\gamma}, \end{equation*} with \alpha = 0 and \gamma = -7/4 .
