The dependence of the novel properties observed in colossal magnetoresistance (CMR) materials, other than average ionic radii 〈rA〉 and Mn valence ratio (Mn3+/Mn4+), was investigated through examination of the transport and magnetic properties of Pr0.65(Ca0.7Sr0.3)0.35MnO3, La0.123Pr0.527(Ca0.8Sr0.2)0.35MnO3, and Pr0.65(Ca0.866Ba0.134)0.35MnO3. The average ionic radii 〈rA〉 and valence ratio of all three samples have been kept equal. The results of this investigation indicate a more intense role of the nature of individual A-site cation and the lattice mismatch. A remarkably large magnetoresistance of the order of 108 at moderate magnetic field has been observed for Ba-doped sample.
