Аннотация доклада:
The research of Sm0.55Sr0.45MnO3 have shown that there's a magnetic inhomogeneous state consisted of three types clusters:ferromagnetic, A- and CE-type antiferromagnetic (CE-AF)with tedmperature Neel T_NCE = 240 K. We investigated the thermopower alfa and magnetothermopower delta-alfa/alfa. The them temperature dependence have board maximum included T_NCE for the first and the sharp giant minimum located near T_NCE for the second. Sharp decrease of alfa in T_NCE under the the action of magnetic field is connected to destruction of CE-AF phase and shows on its big contribution in alfa.
