Abstract: Polycrystalline samples La 0.7− x Nd x Sr 0.3 Mn 0.7 Ti 0.3 O 3 ( x =0.10; 0.20 and 0.30) were prepared by a high-temperature solid-state reaction technique. The X-ray diffraction shows that all the samples crystallize in the orthorhombic structure, Pbnm space group, with presence of a minor unreacted Nd 2 O 3 . The electrical response was studied by impedance complex spectroscopy over a broad frequency range (40–100 MHz) at room temperature. The values of ac conductivity for all samples were fitted by the Jonscher law σ ( ω ) = σ dc + A ω s . For x =0.10 and 0.20, hopping occurs between neighboring sites, whereas for x =0.30 the hopping process occurs through longer distance. Complex impedance plots exhibit semicircular arcs described by an electrical equivalent circuit, which indicates that the Nd-doped compounds obey a non-Debye relaxation process.
