Magnetic ordered states of an .5=1 Ising antifer'ronaagnet with a uniaxialanisotropy D-term which causes a sjnglet ground state: in the absence of exterxaalmagnetic field are investigated by the naean field thec?ry. The dependence of 1.hecritical temperatures on a uniaxial anisotropy and fate H-T phase diagrams forvarious values of anisotropy paranaeter are calcrnlateci. In a certain rauage of D-term, there appears a novel kind of phase diagrams where the first-order phasetransition, the critical endpojnt, and the bicritical csndpoint can be seen. l'hebehaviors of free eraergy of the present systena with several phases are also given.
