Description
We report the results from transport and magnetic measurements on Sr2-x La x FeMoO6 and Sr2-x Ba x FeMoO6 . The temperature and electronic doping dependence of the thermoelectric power of Sr2-x La x FeMoO6 is remarkably similar to that observed in the superconducting cuprates. The low-field magneto-resistance decreases with increasing La concentration and we show that it can be modeled by a grain boundary magnetization that is different from the bulk magnetization. The maximum negative magneto-resistance (∼-25% at 0.8 T) occurs in the Ba2FeMoO6 sample that has the largest resistivity
