The temperature dependences of the thermoelectric power, TEP,(S) and magnetoresistance (MR) effect of La1-xLixMnOy (x= 0.05, 0.1, 0.15, 0.2 & 0.25 at%) fixed valence doped compounds were studied between 80K and 320K. X-ray powder diffraction (XRD) showed that the samples are single phase. We found the correlation of structures to the magnetoresistance (MR) and the thermoelectric power (S) which we assigned to change the specific branches of the magnon/phonon spectra with x. We also observed a splitting of the Curie and the metal insulating temperature TC> Tms.
