The effects of the anisotropic exchange interactions on the magnetic orderedstates, the magnetization and the magnetic susceptibility of the singlet ground statesystem of spin one and with a uniaxial anisotropic D-term are investigated bythe molecular field theory in the vicinity of the level crossing field HzD/gp..It is shown that the induced ordered state without the transverse component ofmagnetization appears in a certain range of magnetic field as the spin dimen-sionality decreases. It has also turned out that the phase transition betweenthis ordered state and the canted antiferromagnetic state ordinarily found forthe isotropic sing[et ground state system is of the first order.
