Abstract : The results of Mössbauer measurements on the intermetallic compounds Fe1-xCox2B 0 ࣘ x < 1, Fe1-xCoxBe 0 ࣘ x ࣘ 0,5 and Fe1-xMnxBe2 0 ࣘ x < 1 are presented. The electron density i. e. the isomer shift at the iron sites remains unchanged for alloying in each of these systems. The hyperfine field values suggest a nearly constant iron moment in Fe1-xCox2B and Fe1-xCoxB, whereas it decreases in Fel-xMnxBe2. The comparison with the average magnetization for the Fe1-xCox2B and Fe1-xMnxBe2 compounds suggests an important decrease in the magnetic moments of Co and Mn atoms, respectively.
