Low-temperature spin dynamics and absence of magnetic order in layered α − RuI 3
Abstract
The honeycomb-lattice system α − RuI 3 is isostructural to the widely studied α − RuCl 3 compound which was identified as a potential Kitaev system but exhibits, instead of spin liquid behavior, a magnetically ordered zigzag ground state which sets in below 14 K. Here we show experimentally that, in contrast, the spins in α − RuI 3 remain dynamic down to at least 50 mK. We study the spin dynamics using muon-spin relaxation methods and determine the presence of low-frequency fluctuations which are characteristic of a two-dimensional system.
