Abstract :
The magnetization of powdered RMn6-xCrxGe 6-compounds (with R=Y, Gd, Tb, Dy, 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 K=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 2μ B. Metamagnetism was observed in compounds with R=Y, Lu. The Mn-Mn distance strongly affects the magnetization curves in these latter eases
