Abstract

We present the electrical properties of polycrystalline La_0.7-xPr_xSr_0.3MnO₃ in which the average ionic radius of the A site 〈r_A〉 is systematically varied while keeping the carrier concentration fixed. Below the Curie temperature T_c, the spin-disorder scattering process has been regarded to play an important role in the resistivity. With decreasing 〈r_A〉, the structure transition from rhombohedral to orthorhombic phase accompanied with the sharp increase in resistivity at T_c and the increase of the activation energies has been observed.
