Description
Materials with strong spin orbit coupling such as IrTe2 frequently exhibit interesting
magnetic and electronic properties. In particular, this material exhibits a structural
phase transition at 270 K into a charge density wave state, which is suppressed when the
parent compound is doped with metals such as Pd, Fe, Pt, Ni, Mn, Cu, or
Co. As this transition is suppressed, superconductivity or magnetic order appears at low
temperatures, depending on the metal dopant. These low temperature properties are of
interest as the high spin-orbit coupling raises the possibility of topological superconducting states or exotic magnetic order. However, despite significant interest in recent years,
the relationship between magnetism and superconductivity in this material system has
not yet been well established. In this talk, we present an investigation of the properties
of doped IrTe2 by muon spin rotation which confirms a spin glass state below 10K for iron doping and demonstrates that the low temperature state of platinum doped IrTe2 is a conventional BCS fully-gapped superconductor.
