We discuss the behaviour of the magneto-resistivity of the heavy fermion compounds CeCu2Si2, UBe13 and CeAl3. At elevated temperatures Δϱ(B)=ϱ(B)−ϱ(0) is negative and follows the predictions of the theory for independent Kondo impurities. Below a characteristics temperature of 15 K (UBe13) resp. 1 K (CeAl3) the investigated Kondo lattice compounds behave markedly different in such a way that the energy scale of the systems, the single ion Kondo temperature TK, becomes itself temperature dependent. At very low T, Δϱ(B) becomes positive which is interpreted as an indication for a coherent ground state of the Kondo lattice.
