Research output: Other contribution


Zero and longitudinal field muon spin relaxation measurements have been performed on the Kondo lattice system CeAgSb2 in the magnetically ordered (T < 10 K) and paramagnetic (T > 10 K) states. The resulting spectra are consistent with a single muon site which senses a unique coherent internal field of 53 mT at low temperatures and dynamic atomic fields, arising from extremely rapid RKKY-dominated paramagnetic fluctuations of the Ce3+ spins, at higher temperatures. Small stepwise increases in the temperature dependence of the muon relaxation rate at 60 and 17 It appear to be coincident with the Kondo temperature and the onset of coherence, respectively.
