We study the ground state and the phase transitions of the bilayered spin-S antiferromagnetic Heisenberg model using the Schwinger boson mean-field theory. The interplane coupling initially stabilizes but eventually destroys the long-range antiferromagnetic order. The transition to the disordered state is continuous for small S, and first order for large S. The latter is consistent with an argument based on spin-wave theory. \textcopyright{} 1996 The American Physical Society.
