摘要：
Advancing the early work in which a discontinuity of hyperfine fields at Fe-57 nuclei in bulk iron and in aerosol Fe nanoparticles has been revealed by analyzing their Mossbauer spectra the present Letter evidences that the existence of several peaks in the hyperfine distribution (HFD) for bulk Fe is caused with the internal magnetic fields owing to its multidomain structure whereas aerosol Fe nanoparticles are single-domain and show only a unique peak in HFD. This argument has been corroborated by transformation of the HFD pattern for Fe foil after applying the external magnetic field of 0.03 T. (C) 2011 Elsevier B.V. All rights reserved.
