Sizable single crystals of $BaFe_2As_2$ have been grown with self-fluxmethod. The crystals are plate-like with c-axis perpendicular to the plane. Thesize can be as large as 3 x 5 x 0.2 $mm^3$. The resistivity anisotropy($\rho_c/\rho_{ab}$) is as large as about 150, and independent of temperature.The transport in ab plane and along c-axis direction shares the same scatteringmechanism. In contrast to the magnetic behavior of polycrystalline samples, noCurie-Weiss behavior are observed, a temperature linear dependentsusceptibility occurs above spin-density-wave (SDW) transition. Thesusceptibility behavior is very similar to that of antiferromagnetic SDWchromium. Magnetic behavior of single crystal definitely gives evidence forexistence of local moment except for the contribution to susceptibility fromitinerant electrons. A resistivity minimum strongly dependent on magnetic fieldis observed. A log(1/T) divergency, similar to that of the underdoped cuprates,happens at low temperature. Here we first present intrinsic transport andmagnetic properties, and their anisotropy from high quality single crystal.
