Local magnetism and spin dynamics of the frustrated honeycomb rhodate

Abstract:

We report magnetization, heat capacity, 7Li nuclear magnetic resonance (NMR) and muon-spin rotation (μSR) measurements on the honeycomb 4d^5 spin liquid candidate Li2RhO3. The magnetization in small magnetic fields provides evidence for a partial spin freezing of a small fraction of Rh^4+ moments at 6 K whereas the Curie-Weiss behavior above 100 K suggests a pseudo-spin–1/2 paramagnet with a moment of about 2.2 μB. The magnetic specific heat (Cm) exhibits no field dependence and demonstrates ...
