NMR Study of Single Crystal CeVGe₃

CeVGe3 is a heavy fermion antiferromagnet with TN ~ 6 K and a hexagonal unit cell. The small ratio of TN to the Curie-Weiss temperature in this material may point to a role for geometric frustration. We present nuclear magnetic resonance (NMR) of 51V in a single-crystal. Measurements of the Knight shift and spin-lattice relaxation rate (T1), performed at 11.7 Tesla both parallel to the c axis and in the a-b plane, highlight the antiferromagnetic transition and reveal a significant Knight shift anomaly. Broadening of the NMR spectra at low temperatures in the ordered phase suggest incommensurate magnetic ordering of the Ce.
