Abstract :

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 4Ã?Â?5Ã?Â?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.
