摘要：

The magnetization of powdered RMn6-xCrxGe6-compounds (with R = Y, Gd, Tb, Dv, Ho, Er, Lu) was studied at 4.2 K in high magnetic fields up to 38 T. From the high field data values for the Mn-moments were obtained for compounds with R = Y, Gd, Tb , Dy whereas the R-Mn coupling constants were estimated for the compounds with R = Gd, Tb, Dy. The Mn-moments were found to be approximately 2mu(B). Metamagnetism was observed in compounds with R = Y, Lu. The Mn-Mn distance strongly affects the magnetization curves in these latter cases.
