Spin-liquid ground state on the perfect kagome lattice in YCu3(OH)6Cl3

Abstract: Although spin-liquid ground state (GS) of a quantum kagome antiferromagnet has been well accepted, its exact nature remains elusive. Partially, this is due to theory being unable to grasp the GS, partially, the reason is in kagome representatives that are inevitably imperfect. Therefore, in-depth investigations of novel kagome compounds are highly desired. We propose a muSR study of the recently discovered YCu3(OH)6Cl3 with a perfect kagome structure that so far lacks any sign of magnetic ordering. Importantly, contrary to the kagome paradigm herbertsmithite, it absences any appreciable anti-site disorder. The muSR study should provide a valuable microscopic probe to confirm the expected spin-liquid GS and to address its exact nature. Control measurements are planned on structurally similar Y3Cu9(OH)19Cl8 with slight distortion of the kagome lattice and magnetic order below TN = 2.2 K.
