Abstract: A Missbauer polarimeter consists of a gamma ray source (polarizer),transmitter (sample to be analyzed),analyzer and automatic counting system. This equipment was used to observe the Mssbauer Faraday effect in non- stoichiometric FesO4 Experimental results demonstrated that electronic hopping above the Verwey temperature between Fe2+- Fe3+ ions on the octahedral sites is a only localized phenomenon and the recoilless fractions of Fe nuclei in Fe3-vO4 (v=0.02) are 0.71 for A sites and 0.62 for B sites, respectively.

Key words: Mssbauer polarimeter, Faraday effect
