Low Temperature Thermoelectric Power Properties in La2.1Sr1.9Mn3O10 System
Temperature dependent thermoelectric power (TEP) of La$_{2.1}$ Sr$_{1.9}$ Mn$_3$O$_{10}$ system has been studied in the temperature range 80-373 K. In the low temperature ferromagnetic regime, TEP (S) follows an expression of formS=S$_{0}$ +S$_{1.5}$ T$^{1.5}$ +S$_4$T$^4$ over the wide range of temperature. The broad peak below the ferromagnetic transition and complicated temperature dependence of S may be understood on the basis of electron-magnon scattering as predicted for an itinerant ferromagnet. High temperature TEP data can be well fitted with Mott's small polaron hopping model.
Key words: Electron-magnon scattering, Hopping, Small polaron, Thermoelectric power
