Abstract
NMR spectra of Fe-57 nuclei in single crystals of BaFe12O19 and Ba(Fe2 -xCox)Fe16O27 (x = 0, 0.8) were measured at 4.2 K. The field dependenc e of the resonant frequency at iron site 4f(VI)(R) in external magneti c fields parallel and perpendicular to the hexagonal axis was used to trace the magnetization processes. The change of the easy direction wi th Co content was determined from the results.
