The spherical model method which simplifies the calculation in the Ising model is examined by use of the Laplace transformation. This method is applied to the antiferromagnetic case by dividing the lattice points into two sub lattices, and the magnetic susceptibilities and critical field etc. are obtained. Also the application to the face-centered lattice is made and only an expressions for entropy and energy at high temperatures are obtained.
