We show that the mean-field phase diagram of the realistic spin-orbital model derived for a perovskite lattice in three dimensions consists of four different classical magnetic phases which become degenerate at orbital degeneracy. The quantum fluctuations are drastically enhanced and suppress the classical long-range order, providing a new mechanism to stabilize a quantum spin liquid near the multicritical point.
