抄録

Electrical resistivities, Hall coefficients, and thermoelectric powers have been measured for polycrystalline samples of LaFe_1−yCo_yAsO_1−xF_x (x=0.11) with various values of y. The results show that there exists a clear distinction of these transport behaviors between the superconducting and nonsuperconducting metallic regions of y divided by the boundary value y_c∼0.05. We have found that the behaviors in both regions are very similar to those of high-T_c Cu oxides in the corresponding phases. If they reflect, as in the case of Cu oxides, the effects of strong magnetic fluctuations, the energy scale of the fluctuations is considered to be smaller than that of the high-T_c Cu oxides by a factor of ∼1⁄2. Arguments on the electronic nature and superconducting symmetry are presented on the basis of the observed small rate of the T_c suppression caused by Co doping.
