NMR investigation of Kitaev spin liquid candidate material Cu<sub>2</sub>IrO<sub>3</sub>

ORAL

Abstract

Cu2IrO3 is a Kitaev spin liquid candidate material [1]. In this talk, we report 63,65Cu high-field Nuclear Magnetic Resonance (NMR) measurements of Cu2IrO3 [2]. We probed the intrinsic spin susceptibility based on 63,65Cu Knight shift, and the magnetic field effects on paramagnetic spin dynamics based on NMR relaxation rate 1/T1.
