Magnetocrystalline anisotropy, Curie temperatures, spin reorientation temperatures, and first-order magnetization processes (FOMP) are reported for RFe{sub 10}Si{sub 2} compounds with R=Y, Gd, Tb, Dy, Ho, Er, and Lu. The saturation magnetizations of them at 1.5 K are determined. The value of the R-Fe magnetic-coupling constant {ital J}{sub RFe}/{ital k}, derived by a mean-field analysis of the Curie temperatures, is about {minus}10 K. A tentative spin-phase diagram for the RFe{sub 10}Si{sub 2} series is presented.
