It is shown that ferromagnetism and insulator to metal transitions in small A site cation manganites Pr1−xCaxMnO3 are induced by rhodium doping. Colossal magnetoresistance properties are evidenced for a large compositional range (0.35⩽x<0.60). The ability of rhodium to induce such properties is compared to the results obtained by chromium and ruthenium doping. Models are proposed to explain this behavior.
