合成橄榄石Mn 2SiS 4在83 ~ 86 K之间出现一个狭窄的自发磁化区域。中子衍射分析表明，锰离子沿晶轴沿着具有反铁磁自旋取向，在两个不同对称性的位置上具有相反的铁磁成分，即反转和镜像。在83 K以下，分析表明倾斜反铁磁性在4.2K时发展到沿b轴共线排列。
A narrow region of spontaneous magnetization was found to occur in the synthetic olivine Mn2SiS4between 83 and 86 K. Neutron diffraction analysis shows that for the manganese ions there is antiferromagnetic spin alignment along the crystallographica-axis, with opposing ferromagneticc-components on two sites of different symmetries, inversion and mirror. Below 83 K the analysis shows canted antiferromagnetism progressing to collinear alignment on theb-axis at 4.2 K.
