A method based on the variation of the magnetization direction of each layer is presented to estimate the magnetization configuration in a superlattice of quantum ferromagnetic system with an interface between perpendicular and in-plane easy-axes layers. The present discrete quantum ferromagnetic model shows a strong quantum fluctuation when the spin S is small. The spin reconstruction due to the anisotropic term from single ion could be quited for S = ½. Numerical results on the magnetization configurations under different applied magnetic fields, critical field and critical anisotropic parameter inducing the spin deviation are presented.
