Title: NMR Knight shift anisotropy in URu 2Si 2: no evidence for nonlinear susceptibility

URu 2Si 2 exhibits an anomalous peak in the nonlinear magnetic susceptibility at the hidden order transition. In order to investigate this anomaly, we conducted direct magnetization measurements and investigated the detailed angular dependence of the 29Si nuclear magnetic resonance Knight shift tensor. We nd that the nonlinear magnetization is smaller than previously reported, and the analogous nonlinear Knight shift tensor is below the detection limit. Our results suggest that the magnitude of the anomalous peak is sample dependent.
