Abstract:
The correlation between structure, Curie temperature (TC), line width of EPR spectra and
electrical conductivity of Pr1-xPbxMnO3 ( x = 0.1, 0.2, 0.3, 0.4, and 0.5) perovskites is discussed. It was
shown that both adiabatic small polaron and variable range hopping models are good for description of
conductivity in paramagnetic region but the first one is more suitable for interpretation of temperature
dependence of EPR line width in temperature range 1.2 TC<T<1.3 TC. ?? 2006 Elsevier B.V. All rights
