Abstract

A series of Al3 + -substituted ε-Fe2O3 nanomagnets, ε-Al x Fe2 − x O3 (x = 0, 0.21, 0.40), with large coercive field values was studied by 57Fe Mössbauer spectroscopy. The hyperfine field and absorption coefficient in the Mössbauer spectra changed with x. These behaviors can be explained by the selective replacement of Fe3 +  ions with Al3 +  ions. This is the first report on the Mössbauer spectra of metal-substituted ε-Fe2O3.
