Although this structure is typically described in terms of an fcc Bravais lattice with a 4 atom basis, it can be viewed more simply as a variant of bcc or B2 in which planes of X$_2$ alternate with planes of YZ along the 001 direction. Using ab-initio electronic structure calculations, we have investigated planar insertions along 001 into the L2$_1$ structure. For most scenarios, insertion of single or double atomic layers of Cr into Co$_2$MnGe or Co$_2$MnSi did not destroy the half-metallic property.
