Summary

Resonance absorption of57Fe 14.4 keV γ-rays by Fe2−xGe compounds is investigated. These compounds are ferromagnetic, and contain two kinds of iron atoms, at whose nuclei induction is different. The separation of multiplets and the probability of Mössbauer effect result to be dependent on the iron content of the compound and are measured forx in the range 0.5÷0.3. The results are discussed and compared with evidence from X-ray diffraction, polarized-neutron diffraction, and magnetic measurements.

Riassunto

Vengono esaminate le caratteristiche dello spettro di assorbimento in risonanza per i γ da 14.4 keV del57Fe da parte di composti del tipo Fe2−xGe, conx compreso nell’intervallo tra 0.3 e 0.5. Detti composti sono ferromagnetici e sono caratterizzati da due tipi di atomi di ferro, per i quali l’induzione al nucleo è differente. La separazione dei multipletti e la probabilità dell’effetto Mössbauer risultano dipendenti dal contenuto in ferro del composto. I risultati sono discussi e confrontati con quelli ricavati mediante diffrazione dei raggi X, diffrazione neutronica e misure di magnetizzazione.
