Abstract
A method for estimating nanoparticle size by determining the distribution function p(H n ) of hyperfine magnetic fields from data on the Mössbauer spectrum of 57Fe nuclei is described. The idea of the method stems from the fact that, owing to the breaking of exchange bonds for surface atoms, their contribution to the total area bounded by the p(H n ) curve can be singled out. The potentialities of the method are illustrated using the data obtained in experiments with nanoparticles of magnetite.Keywords
