Abstract

We have performed a susceptibility M/H and ¹¹B NMR measurements to investigate the static magnetic anisotropy of a single crystal UNi₄B. The Knight shift ¹¹K and the hyperfine coupling constant A_hf evaluated by ¹¹K-M/H plot show anisotropic behavior between H∥[112¯0] and H∥[0001], reflecting the bulk susceptibility. The evaluated transferred term A_tr of A_hf for H∥[112¯0] is much larger than the one for H∥[0001]. The strong hybridization in the [0001]-plane due to a itinerant 5f-electron is strongly associated with the unique magnetic structure in this compound.
