Abstract
Enriched Fe2MoO4 spinel was studied by Mossbauer spectroscopy in the temperature interval of 77-732K. The electrical conductivity measurements were carried out in the temperature range 298-475K. From these studies, it was concluded that fast electron exchange takes place amongst Fe3+ and Fe2+ ions situated at A as well as at B sites in the spinel lattice. The transition temperature TN=350K was determined by the temperature scanning method.
