Abstract

We present a detailed μSR study of the recently synthesized compound, [NH4]2[C7H14N][V7O6F18] (DQVOF), a geometrically frustrated magnetic material, both in longitudinal and transverse configurations. The μSR measurements in zero and longitudinal field show that there is no spin freezing down to 20 mK which is the key requirement for a quantum spin liquid state. Further experiments in transverse field single out two contributions with different shift and broadening which shed a new light on the location of the muons stopping sites.
