The electronic structures of YMn.Ge., LaMn.Ge. and LaCo.Ge. were calculated bythe KKR method in the framework of the LSD approximation. The electronic struc-Lures of the three compounds are similar and in these structures we can see thecharacteristics of the .5, p and d bands of the constituent atoms for ThCr.Si. type com-pounds. Using these electronic structures, we can roughly guess the magnetism ofother compounds by the rigid-band-model; YMn.Si, LaMn.Si,z and LaCo.Si. are anantiferromagnet, a ferromagnet and a paramagnet, respectively. We find also that it isvery delicate whether or not the Fe in RFe.X. (R=Y, La and X=Si, Ge) carries amagnetic moment, as indicated by the experimental results.
