For the AlB2-type solid solutions formed in the quaternary systems R–Ag–Al–Ge (R = Ce, Pr, Nd) magnetic measurements have been performed in the magnetic fields up to5 T and in the temperature range 1.72‑400 K. It is shown that these compounds fit to a Curie-Weiss expression above 80 K. The magnetic characteristics of the compounds (ordering temperature, Curie-Weiss temperature, effective magnetic moment, high-field magnetic moment) have been determined. The effective paramagnetic moments are close to the values of free R3+ (R = Ce, Pr, Nd) ions.
