Strong Magnetic Frustration in Honeycomb System Ag3LiRu2O6

Abstract: Ag3LiRu2O6 is a honeycomb transition metal oxide compound that is remarkable for the complete absence of long range spin order despite a strong magnetic susceptibility of ~2.5 uB/Ru-ion and a Curie-Weiss temperature of TW = –41K. Intriguingly, our preliminary NMR measurements reveal a divergence in the 1/T1 relaxation rate below T = 10K, indicative of spin fluctuations, suggesting the presence of strong magnetic frustration. We propose to use inelastic neutron scattering to uncover the underlying spin dynamics of Ag3LiRu2O6 and better understand the nature of magnetic frustration in honeycomb systems. Based upon our initial characterisation, we suspect that the spin wave gap is on the order of 30meV, making the time-of-flight spectrometer MERLIN an ideal instrument to investigate the Q-dependent magnetic excitation spectrum of Ag3LiRu2O6.
