Abstract

A systematic investigation of polycrystalline La0.7Ba0.1Sr0.2Mn1-xCuxO3 (x = 0 and 0.5) manganite has been conducted with a view to understand the effect of copper substitution on the electrical transport properties and its correlation with structural and morphological properties. The structural and morphological properties of the sample without copper content (x = 0) have been reported previously, while in this research, the structural and morphological properties of sample with 5% copper content (x = 0.5) will be reported. Structural comparison with previous research shows that 5% copper content does not change the rhombohedral structure of the sample without copper content. Comparison of resistivity (ρ) data with the theoretical model shows that the electrical properties of both samples are well described using the electron-electron, electron-phonon, electron-magnon, and kondo-like spin dependent scattering theory. Furthermore, percolation theory which has been used in the model shows that ferromagnetic phase and paramagnetic phase coexisted in both samples. Through copper substitution, the overall resistivity of the sample decreases compared to the sample without copper content. Furthermore, percolation theory demonstrates that ferromagnetic phase of the sample is decreasing as copper ions substituted manganese ion.
