Abstract

The effect of nickel substitution on the electrical transport properties of La0.7Sr0.2Ba0.1Mn1-xNixO3 (x = 0 and 0.1) manganite have been studied. The temperature dependence of resistivity of the samples shows that nickel substitution increases the overall resistivity. Exchange probability calculation shows that the ferromagnetic (FM) coupling inside the sample decreases upon nickel substitution, which induces antiferromagnetic (AFM) coupling inside the sample. These results are suitable with the reduction in the electronic bandwidth value. Comparison of experimental data with theoretical models shows that the electrical behavior of the samples is well explained by a theory based on percolation models. Present result suggests that the electrical behavior of the sample was influenced by scattering and interaction between electron, phonon, and magnon. Nickel substitution also decrease the metal-insulator transition temperature and theoretical Curie temperature from around 328 K to 249 K and around 349 K to 275 K respectively.
