Аннотация доклада:
In this work thermopower S, magnetothermopower DS/S, electrical resistivity ro and magnetoresistance DR/R were studied in single-crystals Nd(1-x)SrxMnO3 (x=0.15, 0.2, 0.3). The study of the magnetic properties of these compounds showed that they consist of ferromagnetic clusters located in A-type antiferromagnetic clusters located in A-type antiferromagnetic matrix. Giant negative magneroresistance, which was observed in these compounds, indicates that these ferromagnetic clusters belong to ferron type. A sharp increase of S and negative DS/S were discover near Curie point were DS/S=94%. This means that thermopower is caused by by presence of ferrons. Therefore thermopower in doped magnetic semiconductors is determined by the doping level and volume of the sample.
