Magnetic transition induced by mechanical deformation in Fe_(60)Al_(40-x)Si_x ternary alloys

摘要

We have used Mossbauer spectroscopy and X-ray diffraction to study the influence of different Al/Si ratios on the structural and magnetic properties of the mechanically deformed Fe_(60)Al_(40-x)Si_x alloys. The results indicate that ternary alloys also present the magnetic transition with disordering observed in bin ary Fe_(60)Al_(40) alloys. Besides, Si introduction has two opposite contributions. From a structural point of view, hinders the disordering process, but, from a magnetic point of view promotes the magnetic transition.
