Evidence for spin liquid ground state in SrDy2O4 frustrated magnet probed by muSR
Abstract
Muon spin relaxation (μSR) measurements were carried out on SrDy2O4, a frustrated magnet featuring short range magnetic correlations at low temperatures. Zero-field muon spin depolarization measurements demonstrate that fast magnetic fluctuations are present from T=300 K down to 20 mK. The coexistence of short range magnetic correlations and fluctuations at T=20 mK indicates that SrDy2O4 features a spin liquid ground state. Large longitudinal fields affect weakly the muon spin depolarization, also suggesting the presence of fast fluctuations. For a longitudinal field of μ0H=2 T, a non-relaxing asymmetry contribution appears below T=6 K, indicating considerable slowing down of the magnetic fluctuations as field-induced magnetically-ordered phases are approached.
