Abstract: | The domain wall NMR spectra of57Fe were measured on polycrystalline samples of BaFe12O19 and SrFe12O19 at 4·2 K. We have calculated the anisotropy of the hyperfine field dipolar component. The measured NMR spectra were interpreted supposing that the hyperfine field anisotropy is caused only by the dipolar field anisotropy. |
