Abstract: For the first time the exchange interaction of Ruderm-Kittel-Kasuya-Yosida (RKKY) type is studied semi-empiriсallyin compounds of binary systems of rare –earthmetal (REM)-weakly magnetic metal (WMM) (REM=Gd,Tb,Dy,Ho,Er,Tm; WMM=Al,In) using experimental values of paramagnetic Curie temperature (?_P)of these compounds. The prediction of theory of RKKY about existence of direct proportional dependence of experimental values of ?_Pon de Gennes factor for equiatomic compounds of heavy REM with WMM similar pure REM.As a whole, it is found that for REM compounds with WMM as well as for pure REM the exchange interaction of RKKY type is characteristic.

Key words: exachange interaction, magnetic susceptibility, paramagnetic temperature, magnetic moment, de Gennes factor.
