Quantum Spin Liquid in triangular Seff=1/2 rare-earth based antiferromagnets

DOI

The rise of quantum materials observed in the past decades has been a source of great excitement for condensed matter scientists, with the flourishing of new concepts and electronic phases of matter. In particular the Quantum Spin Liquid (QSL) state has attracted a lot of attention as it shows intriguing collective phenomena such as fractionalized excitations or emergent gauge fields. A new Seff=1/2 rare-earth based material, YbMgGaO4, was recently shown to avoid any spin freezing down to T = 50mK and to display a continuum of excitations. However, the presence of intersite mixing between Mg2+ and Ga3+ has dramatic effects on these low energy excitations. Here, we propose to use µSR spectroscopy to confirm two new Seff=1/2 triangular compounds (KYbVO and KCsYbPO) that are free of such defects as quantum spin liquid candidates and further probe their spin dynamics at low temperatures.
