A Mössbauer 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 Mössbauer Faraday effect in non- stoichiometric Fe₃O₄. 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 ⁵⁷Fe nuclei in Fe_3-vO₄ (v = 0.02) are 0.71 for A sites and 0.62 for B sites, respectively.
