Kim, M. S.
We have carried out 119Sn nuclear magnetic resonance (NMR) measurements on the quasi-Kagomé compound CeRhSn. We found that 119Sn Knight shift (119K) is highly anisotropic and shows Curie-Weiss type temperature (T) dependence above 25 K. In this T range, the NMR relaxation rate shows 119(1/T1)α√T and is enhanced by magnetic fluctuations. At low T's, 119K stays constant and the enhanced Korringa relation of 119(T1TK2) = const is observed, differently from the non-Fermi-liquid behavior observed for bulk measurements. The present NMR results suggest that antiferromagnetic spin fluctuations exist in CeRhSn.
