Fractionalized spinon excitations in quantum spin liquid YbMgGaO4
YbMgGaO4 is a recently discovered quantum spin liquid material with S = 1/2 Yb3+ ions arranged in a perfect triangular lattice. This configuration gives rise to strong frustration and prevents the formation of magnetic order down to 50 mK in spite of effective antiferromagnetic exchange interaction of J/kB = -4 K. We propose to measure its spin exchange interactions and the fractionalized magnetic excitations called spinons.
