Abstract There are various methods to produce iron based nano crystalline magnetic alloys. Among these methods, mechanical alloying is one of the most important. In this research, nano crystalline Fe85Si10Ni5 soft magnetic alloy was synthesized by mechanical alloying. The effect of alloying time on phase constituents and magnetic properties of the produced powders was investigated, by X-ray di...
In this study, for the first time, cobalt base ribbons were made by adding two different amounts of tungsten with Co67.7Fe4W0.8Si16.5B11 and Co66.5Fe4W2 Si16.5B11 compounds by melt spinning in the water. The pattern of X-ray diffraction taken from these ribbons shows that these magnetic ribbons are amorphous. By using thermal analysis curves, taken from the ribbons, crystallization temperature...

The kinetics of nanocrystallization of a Mn-doped FINEMET alloy from its amorphous precursor is reported. The alloy studied was of a composition (Fe1 Mn )73 5Nb3CuSi13 5B9 where = 0 05. X-ray diffraction (XRD) confirmed that -FeSi is the product of primary nanocrystallization. Crystallization kinetics were studied using time-dependent magnetization, ( ), as a measure of the volume fraction crys...
In this work, La0.6Sr0.4MnO3 manganite particles with nano and micro scales were prepared by Sol-gel and solid state reaction methods. The results from X-ray diffraction analysis by Fullprof software showed that the samples have been crystallized in the rhombohedral structure with (R-3C) space group. Investigation of magnetic properties showed that this compound belong to soft ferromagnetic mat...
