Exponent 1/4 from the mean field approximation
Abstract
Description
We consider the magnetization of the three-dimensional ferromagnetic near the critical temperature in the mean field approximation. It is found that for some directions of easy magnetization one obtains exponent 1/4 instead of the usual 1/2.
