摘要
As a member of transition metal dichalcogenides, IrTe2 is expected to exhibit typical layered structure and show large spin-orbital coupling (SOC) due to the large atomic numbers of Ir and Te. We successfully fabricated high quality IrTe2 crystals, where superconductivity was detected by transport and diamagnetic measurements. Furthermore, linear magnetoresistance was observed over a wide range of magnetic field up to 15 T without any sign of becoming saturated, which might originate from topological nontrivial state. Thus, IrTe2 could be a candidate of topological superconductors with simple element composition and crystal structure.
