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 Ahf evaluated by 11K-M/H plot show anisotropic behavior between H∥[112¯0] and H∥[0001], reflecting the bulk susceptibility. The evaluated transferred term Atr of Ahf 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.
