Figure 2 (IMAGE) Institute for Basic Science Caption Crystal structure of topological magnet Mn3Si2Te6 (upper left). It has a unique structure where Mn atoms (red) are intercalated between Te atom (grey) layers. Mn atoms in basic and intercalated structures are labeled as Mn1 (upper right) and Mn2 (lower right) layers, respectively. Each layer has a different spin moment and direction, which results in ferrimagnetic ordering. An optical image of Mn3Si2Te6 is shown in the lower left panel.
