摘要：

A narrow region of spontaneous magnetization was found to occur in the synthetic olivine Mn2SiS4 between 83 and 86 K. Neutron diffraction analysis shows that for the manganese ions there is antiferromagnetic spin alignment along the crystallographic a-axis, with opposing ferromagnetic c-components on two sites of different symmetries, inversion and mirror. Below 83 K the analysis shows canted antiferromagnetism progressing to collinear alignment on the b-axis at 4.2 K.
