By the amalgam process, which consists of a heat treatment of amalgams and yields mercury-free alloys and intermetallic compounds, rare earth metal RE Y, La, Ce, Pr, Nd, Sm, Gd, Dy, Ho, Er-manganese intermetallic compounds have been prepared. The lattice spacings and the structures of the compounds REMn2, RE6Mn23, and REMn12 were determined. The phase diagrams of the systems Gd-Mn, Dy-Mn, Ho-Mn, and Er-Mn are given. By magnetic measurements in the temperature range from 80 to 1500K the magnetization, susceptibility, and the Bohr-magneton numbers of these compounds are evaluated. The magnetic behavior of these compounds can be understood by a mutual interaction of different ferrimagnetic states.
