摘要: Abstract Mossbauer and magnetization studies of the Fe 25 Se 75 alloys produced by mechanical alloying were performed in order to access chemical structure iron selenides. The 57 spectroscopy (MS) results showed a doublet paramagnetic FeSe 2 alloy spectra for samples milled from 3 52 h. For milling times longer than 52 h, MS formation high-temperature 7 8 selenide, which is ferrimagnetic phase, together with compound that paramagnetic. measurements same at room temperature corroborate these small values saturation phase.
