Spin liquid state in a novel rare-earth based triangular lattice antiferromagnet NdTa7O19

Abstract: Rare-earth based geometrically frustrated magnets represent a promising new platform for the search of enigmatic quantum spin liquids. Here, the entanglement of spin and orbital degrees of freedom is believed to be one of the crucial factors that can stabilize this disordered, yet highly quantum-entangled ground state. In our study, we focus on a novel triangular lattice antiferromagnet NdTa7O19, where such effects might take place. Our preliminary bulk magnetic characterizations indicate a lack of any magnetic ordering or freezing in this material. This prompts the need of more sensitive local-probe magnetic investigations that could unambiguously confirm the spin-liquid ground state and characterize the corresponding magnetic excitations. The muSR study performed far down to sub-kelvin temperatures should provide a valuable microscopic probe to confirm the spin-liquid conjecture.
