The magnetic and transport properties of mixed-valence manganites La 0.7-xSmxPb0.3MnO3 (x = 0,0.1 and 0.3) are investigated. The x = 0 phase is indexed in a rhombohedral structure (R3̄c) while the rest exhibit orthorhombic symmetry (Pnma). The increase of x causes a decrease in the spin-coupling interaction between the moments of Mn. Hence, the decrease of ferromagnetic transition temperature from 321 to 152 K and the saturation magnetization from 80.36 to 78.33 emu/g can be affected by the substitution of La by Sm.
