摘要：

Magnetic measurements on the R(Co1-xMnx)2 Laves phase systems with R = Gd, Tb, Dy, Ho, Er, Tm have been performed. A strengthening of the RCo2 ferrimagnetism shows up through a rapid increase at small Mn concentration x of the Curie temperature which reaches a maximum for x around 0.25. The results are interpreted by invoking the sole peculiarities of the d-magnetism keeping the R-R and R-d exchange integrals invariable on x.
