Layered IrTe2 is known to exhibit extremely rich physical properties with two successive phase transitions at T1 ~ 280 K and T2 ~ 180 K. We have grown IrTe2 single crystals with typical sizes of 4×5×1.2 mm3. This allows us to experimentally investigate its physical properties along different directions. We report the anisotropy of intrinsic transport and magnetic properties of IrTe2 single crystals. The resistivity anisotropy ( ) is more than 200. The results also show the in-plane Fermi-liquid behavior. In contrast, the magnetic properties are more or less isotropic below T1. What is particularly interesting is that we observe superconducting transition at Tc ~ 2.3 K. This indicates that both structural (at T1 and T2) and superconducting (at Tc) transitions can coexist in this system. The implications will be discussed.
