 Abstract: The transport and superconducting properties of Ba(1-x)K(x)Fe(2)As(2) single crystals were studied. Both in-plane and out-of-plane resistivity were measured by Montgomery method. The in-plain resistivity temperature dependence was found to be nonlinear with the tendency to saturate at high temperature. We have found that the resistivity anisotropy is almost independent of temperature and lies in the range 10-40 for the studied samples. We explain this result by the extrinsic nature of high out-of-plane resistivity, which may be due to the presence of flat defects along Fe-As layers. This statement is supported by comparatively small effective mass anisotropy, obtained from the upper critical field measurements. (C) 2011 The Japan Society of Applied Physics
