The spiral size is reduced in the superlattice with thin CoSi layers (CoSi:MnSi=1:1).
- class="label">•
At a larger CoSi:MnSi=2:1 thickness ratio, the material behaves as a ferromagnet.
- class="label">•
The spin moment and orbital occupancy depend significantly on the thickness of the CoSi layers.

The exchange interaction between Mn atoms appears to be generally impervious to the presence of CoSi.
