Аннотация	Layered intermetallic compounds of the RMn2Si2 family, where R denotes a rare- earth element or yttrium, crystallize in the ThCr2Si2- type structure and have attracted considerable interest due to their complex magnetic ordering and relatively high magnetic transition temperatures [ 1, 2] . In this structure, Mn atoms form two- dimensional square lattices that stack along the crystallographic c- axis, separated by Si and R layers. The magnetism in these compounds is primarily governed by the Mn sublattice and can be finely tuned through chemical substitution or external pressure, yielding a diverse landscape of exchangedriven magnetic transitions [ 3–6] . LaMn2Si2, whichis the focus of this study, adopts a noncollinear magnetic structure, where Mn moments are ferromagnetically aligned along the c- axis while remaining antiferromagnetically coupled within the ab plane [ 4, 7] . This canted spin arrangement breaks the inversion while preserving certain crystallographic symmetries. Calculation results. The non- collinear GGA calculation correctly reproduces the magnetic ground state of LaMn2Si2 refined in [ 4] . The spin moments on Mn are ms = ( ±2. 55, 0, 1. 55) μB, but they compensate each other in the x- direction in the spin space ( such that the x- component of the total moment vanishes) , while m z
