The magnetic phase diagram near the metal-insulator transition (MIT) boundary of NiS2 - xSex was reinvestigated by using single crystals. A well-defined first-order MIT was observed only in the antiferromagnetic ordered phase by simultaneous measurements on electrical resistivity and magnetic neutron diffraction. At the MIT boundary, however, no appreciable change in the staggered moment was observed. Beyond x ≈ 0.6, the thermally induced MIT dramatically broadens and with decreasing temperature the metallic conductivity starts to occur in the paramagnetic phase.
