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.

Zn₆Cu₃(TeO₆)₂(OH)₆ 因其中Cu²+构成完美的笼目晶格（Kagome lattice）且不存在位点混合无序，作为量子自旋液体（quantum spin liquid）候选材料受到了广泛关注。尽管磁化率测试显示在低至2 K的温区内未观测到任何相变迹象，但比热测量结果在5.2 K处呈现出尖锐的反常信号。开展μ子自旋弛豫（Muon spin relaxation）研究对于阐明5.2 K附近的磁行为、并探究该完美笼目晶格的磁基态至关重要。
