Coherent spin states are considered through the spin operator representation in differential equation, which give quantum mechanical potentials. Squeezed spin states are defined through a canonical transformation. The defined concept of squeezed spin states has been applied to a spin system describing a magnetic system with S = 1. The effective Schrodinger equation is obtained and the squeezed potential has been constructed for the model Hamiltonian. It is found that squeezing acts as a symmetry breaking process (C) 2003 Elsevier Science B.V. All rights reserved.
