The magnetic resistance anomaly in the paramagnetic phase of ordered cubic rare earths systems is considered. Within simple model of the free electrons scattering on the localized moments of magnetic ions system in the Born approximation it is shown that the negative temperature coefficient of the resistivity can be attributed to the spin correlations. The condition for the anomaly is formulated, which generalizes the ones known for the crystal field-free systems in the critical region. The conclusions are illustrated by the results of the resistivity calculations for DyAg and their comparison with the experimental data.
