Crystal Synthesis and Frustrated Magnetism in Triangular Lattice CsRESe2 (RE = La–Lu): Quantum Spin Liquid Candidates CsCeSe2 and CsYbSe2
Source abstract
Abstract
A triangular lattice selenide series of rare earths ( RE ), Cs RE Se 2, were synthesized as large single crystals, using a flux growth method. This series stabilized in either trigonal ( R 3̅ m ) or hexagonal ( P 6 3 / mmc ) crystal systems. Physical properties of Cs RE Se 2 were explored by magnetic susceptibility and heat capacity measurements down to 0.4 K. Antiferromagnetic interaction was observed in all magnetic compounds, while no long-range magnetic order was found, indicating the frustrated magnetism. CsDySe 2 presents spin freezing at 0.7 K, revealing a spin-glass state. CsCeSe 2 and CsYbSe 2 present broad peaks at 0.7 and 1.5 K, respectively, in the magnetization, suggesting the short-range interactions between magnetic RE ions. The lack of signature for long-range magnetic order and spin freezing down to 0.4 K in these compounds ( RE = Ce, Yb) implies their candidacy for a quantum spin liquid state.
