Popis:	The NMR spectra of 57Fe nuclei in a barium hexaferrite single crystal were measured by spin-echo technique at 4.2 K. An external magnetic field of 1.4 and 2.7 T was applied in several different directions in the hexagonal plane in order to detect the influence of the hyperfine anisotropy on the resonance line positions. The number of observed NMR lines was found to agree with our prediction, based on the site symmetry analysis. The dependences of the NMR frequencies on the magnetization direction were fitted to determine (after subtracting the dipolar field anisotropy) the hyperfine field anisotropy tensors for each iron site.
