Abstract
We report measurements of magnetothermopower and magnetoresistivity as a function of temperature on RuSr 2Gd 1-xLa xCu 2O 8 (x=0,0.1). The normal-state thermopower shows a dramatic decrease after applying a magnetic field of 5 T, whereas the resistivity shows only a small change after applying the same field. Our results suggest that RuO 2 layers are conducting and the magnetic field induced decrease of the overall thermopower is caused by the decrease of partial thermopower associated with the spin entropy decrease of the carriers in the RuO 2 layers.
