摘要: The magnetic ground state of the pyrochlore Yb2GaSbO7 has not been established. persistent spin fluctuations observed by muon spin-relaxation measurements at low temperatures have adequately explained for this material using existing theories quantum magnetism. Here we report on synthesis and characterisation to revisit nature state. Through DC AC susceptibility, heat capacity, neutron scattering experiments, observe evidence a dynamical that makes promising candidate disorder-induced spin-liquid or spin-singlet behaviour. This is quite fragile, being tuned splayed ferromagnet in modest field μ0Hc ~ 1.5 T.
