Muon spin relaxation ($\ensuremath{\mu}\mathrm{SR}$) experiments on single crystals of the structurally perfect triangular antiferromagnet ${\mathrm{YbMgGaO}}_{4}$ 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 ${\ensuremath{\mu}}^{+}$ spin relaxation rates, which are proportional to the dynamic correlation …
