Perpendicular magnetic anisotropy of Cu$_2$Sb-type MnAlGe and (Mn-Cr)AlGe films was investigated. Films samples with (001)-texture were successfully fabricated onto thermally oxidized silicon substrates. Perpendicualr magnetic anisotropy energy was enhanced with the Cr-substitution for the Mn-site of MnAlGe.
