Disorder-driven quantum spin liquid-like state in the kagome antiferromagnet K2Mg3Co2Si12O30

Abstract: Quantum spin liquid (QSL) refers to a highly entangled quantum state wherein frustration-induced strong quantum fluctuations evade symmetry-breaking phase transitions even at zero kelvin. Recently, quenched randomness offered a novel paradigm in stabilizing quantum-disordered spin-liquid-like states in geometrically frustrated magnets. As bond randomness generates abundant low-energy excitations that mimic a gapless quantum spin liquid, however, spin excitations and dynamics will be distinct from what is expected for the true QSL. To shed light on this issue, diverse frustrated antiferromagnets subject to the quenched disorder deserve to be investigated by microscopic experimental techniques. Here, we propose a muSR study of kagome antiferromagnetic K2Mg3Co2Si12O30, featuring cation disorder between Co2+ and Mg2+.
