Abstract: | Nuclear magnetic resonance of82Br oriented at low temperature in iron has been observed with a sample prepared by ion implantation atT<0.2 K. The asymmetric resonance signal can be decomposed in a broad background signal and a narrow line of FWHM=1.8 (4) MHz which can be attributed to82Br in undisturbed substitutional sites of Fe. From the center frequency of this narrow line (B
ext=0)=201.86(13) MHz we derive the magnetic hyperfine field asB
hf(BrFe)=81.38(6) T. This value is considerably larger than the result of theoretical calculations. |
