The universal charge transport of the Mn oxides in the high temperature limit was investigated. The resistivity and thermopower of the oxides were measured for temperature up to 1000 K. The x-ray diffraction (XRD) analysis was also carried out for the study. The resistivity and thermopowers of the Mn oxides were found to go towards constant values of 7±1 mω cm and -79±3 μV/K and were found to be independent of carrier density and crystal structures.
