This work reports a detailed study of magnetic and transport properties of the manganite compounds ( R1, R2) 0.67( M1, M2) 0.33MnO 3 ( R1, R2=La, Gd, Pr, Tb, Ho; M1, M2=Ca, Sr, Ba). Taking into account that the ferromagnetic-to-paramagnetic and the metallic-to-semiconductor transition temperatures, as well as the magnetoresistance peak temperature, depend on the ionic radius of the A-site cations, < rA>, as well as on the A-site ( A= R1, R2, M1 and M2) cationic size mismatch, σ2( rA), and also on the ratio Mn 3+/Mn 4+, compositions of the samples employed here were chosen to keep these parameters approximately constant. X-ray diffraction patterns indicate that all samples have similar structural characteristics. Experimental results show that they all present similar ferromagnetic-paramagnetic and metallic-semiconductor transition temperatures, as well as similar behavior of the magnetoresistance. We also found evidences of magnetic coupling between rare-earth and Mn moments at low temperatures, while at high temperatures the rare-earth ions have paramagnetic behavior. These results indicate that by controlling the structural parameters and preparation conditions, one can obtain samples with similar magnetic and electrical properties.
