| Abstract: | Nuclear magnetic resonance of175Hf oriented at low temperature in iron has been observed with a sample prepared by ion implantation. The centre frequency of the broad resonance line isv L (B ext = 0)=138.53(36)MHz. Possible origins of the large inhomogeneous line width of FWHM=11.0(1.1) MHz are discussed. A comparison with model calculations for combined magnetic and electric hyperfine interaction indicates that the centre frequency may be interpreted as the magnetic interaction frequency for175Hf in unperturbed substitutional sites of the host iron. With theg-factor of175Hf from literature the magnetic hyperfine field of Hf in Fe is derived asB hf=?64.9(9.3) T fitting well into systematics. |
