Abstract

The thermoelectric power (TEP) of the La214 system doped with trivalent metals (Fe, Ga, Co, Cr, Mn, and Al) was investigated systematically. The TEPs for the samples doped with 3d metals and sp metals show different temperature-dependent behaviours. The broad maximum in the S(T)-T curve notably shifts to higher temperature upon 3d-metal (Fe, Co, Mn, and Cr) doping, while for the sp-metal (Ga and Al) doping, the broad peak is nearly unchanged. Magnetic scattering is proposed as the main factor influencing the TEP. Other possible factors are analysed and discussed in this paper.
