Fractionalized spin excitation and crystal electric field study in the rare-earth triangular quantum spin liquid candidate: YbMgGaO4

Abstract: A new rare-earth triangular quantum spin liquid (QSL) candidate, YbMgGaO4, has an odd number of electrons per unit cell and spin-orbit entangled effective spin-1/2 (Yb3+). Recently, we have, for the first time, successfully synthesized powder samples and grown high-quality single crystals. Our early studies on magnetic property, heat capacity, and electron spin resonance characterizations have been reported. The measurements consistently and clearly suggested that YbMgGaO4 is a potential QSL with a spinon Fermi surface. Further sensitive and unique measurements, such as μSR and inelastic neutron scattering, are highly required to confirm the QSL ground state, explore and characterize the novel low-energy spin excitations at extremely low temperatures.
