Correlation of electrical and thermalphysical properties of La0.85Ag0.15MnO3 manganite

The relationship of electrical and thermal properties of manganites has been traced through the analysis of temperature dependence of the La0.85Ag0.15MnO3 resistivity. The discussion of results has been held on the basis of percolation theory in the framework of the phase-layered manganite. A behavior of the heat capacity, as well as a change in magnetic entropy can be predicted from the analysis of temperature and magnetic-field dependences of resitivity.
