摘要：
Muon spin relaxation (mu SR) experiments on single crystals of the structurally perfect triangular antiferromagnet YbMgGaO4 indicate the absence of both static long-range magnetic order and spin freezing down to 0.048 K in a zero field. Below 0.4 K, the mu(+) spin relaxation rates, which are proportional to the dynamic correlation function of the Yb3+ spins, exhibit temperature-independent plateaus. All these mu SR results unequivocally support the formation of a gapless U(1) quantum spin liquid ground state in the triangular antiferromagnet YbMgGaO4.
