Excitation Spectrum of the Triangular-lattice antiferromagnet (CD3ND3)2NaRuCl6
The prospect of merging the paradigms of geometric frustration on a triangular lattice and bond anisotropies in the strong spin-orbit coupling limit holds tremendous promise in the ongoing hunt for exotic quantum materials. The recently discovered organic quantum magnet (CD3ND3)2NaRuCl6 poses a rare candidate system to realize such physics, displaying a triangular arrangement of Ru3+ ions adopting the spin-orbital entangled j = ½ state. Thermodynamic and magnetometric data suggest a highly frustrated ground state with significant antiferromagnetic correlations but residual magnetic order below TN = 0.22 K. We hereby propose a single-crystal investigation on the magnetic excitation spectrum of (CD3ND3)2NaRuCl6 at zero field and in the fully polarized state, from which we will attempt to determine the effective spin Hamiltonian and pinpoint the relevance of potential bond anisotropies. With an expected bandwidth of ~ 0.5 meV and a suspected presence of continuum excitations, the cold triple-axis spectrometer THALES with the FLATCONE multi-analyzer setup will be ideally suited for this purpose.
