Abstract
A combined nuclear magnetic resonance (NMR) and Mossbauer effect study of YFe10V2 has been carried out. Based on the 57Fe hyperfine fields (HFS) obtained from the Mossbauer results, the resonance lines of the NMR spectrum are assigned and the site preference of V atoms is determined. On the other hand, according to the site preference of vanadium atoms determined by NMR, together with neutron diffraction results, the 57Fe Mossbauer spectrum is fitted. It can be deduced from the NMR results that the existence of one nearest-neighbour Fe atom leads to an increase in the V HF of about 0.35, and the core electron polarization contribution Hcp, the 4s conduction electron polarization contribution Hs and the effect of the second-nearest-neighbour Fe atoms on the HF sites cannot be negligible.
