Investigating the magnetic ground state of Kagome lattice Zn6Cu3(TeO6)2(OH)6

Zn6Cu3(TeO6)2(OH)6, with Cu2+ form a perfect Kagome lattice, and no site-mixing disorder has attracted lots interests as a quantum spin liquid candidate. Although the magnetic susceptibility reveals no sign of phase transition down to 2 K, a sharp anomaly is observed at 5.2 K from specific heat measurements. Muon spin relaxation study is crucial to understand the behavior near 5.2 K and investigate the magnetic ground state of this perfect Kagome lattice.
