摘要
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 dependence of the resonant frequency at iron site 4f(VI)(R) in external magnetic fields parallel and perpendicular to the hexagonal axis was used to trace the magnetization processes. The change of the easy direction with Co content was determined from the results.
