$\mu$SR Investigation of Transition Metal Doped IrTe$_2$

ORAL

Abstract

Materials with strong spin orbit coupling such as IrTe$_2$ 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 supressed when the parent compound is doped with transition metals such as Pd, Fe, Pt, Ni, Mn, Cu, or Co. As this transition is supressed, 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 transition metal doped IrTe$_2$ by $\mu$SR which confirms spin glass behavior for Fe doping and probes the low temperature magnetic states for other transition metal dopants.
