Nuclear magnetic resonance on oriented nuclei of 91 SrFe

Nuclear magnetic resonance on oriented nuclei was used in combination with beta-ray detection and ion implantation, leading to the successful observation of the resonance of 9 1 SrFe. The magnetic hyperfine field (B H F ) was deduced as B H F (SrFe)= -23.83(7) T using the known nuclear g factor. This result explains the existing problem of disagreement in B H F values for SrFe between theory and experiment. An experimental nuclear spin-lattice relaxation rate was obtained and is briefly discussed in comparison with a theoretical estimate.
