Abstract

The structural and electrical transport properties of La 0.67Ba 0.33Mn 1-yTi yO 3 manganite, with y = 0.00, 0.05, 0.10, 0.15, 0.20, 0.40 and 0.60, prepared using the solid state reaction technique have been investigated. The X-ray diffraction spectra of the Ti substituted samples showed the formation of single phase compound with Pm3m cubic structure except for the y = 0.60 sample, which showed La 2Ti 2O 7 phase formation. Lattice parameter increased with Ti content and then decreased at y = 0.60. Resistivity versus temperature study showed that only samples with y = 0.05 and 0.10 exhibited both metallic and semiconductor-like behaviour with the metal-insulator transition temperature, T p of 167 K and 43 K, respectively. At higher Ti concentration the samples only showed the semiconducting behaviour. At T < T p the resistivity curves followed the ρ = ρ o1 + ρ 1T 2 relation and for T > T p, the curves can be fitted with the nearest neighbour hopping (NNH), variable range hopping (VRH) or/and the small polaron hopping (SPH) models.
