Bazı İkili Alaşımların Compton Profile Ölçümleri ve Yük Transferlerinin Belirlenmesi

Magnetic FexNi1-x alloys have an important role in fundamental and

applied research, as they are a soft magnetic material with strong

magnetization, low coercivity, high magnetic permeability, low thermal

expansion and very good corrosion resistance. Due to its widespread use, a complete

understanding of the physical and chemical properties of these alloys is

required. In particular, it is necessary to determine the momentum

distributions and charge transfers of 4s and 3d electrons.<o:p></o:p>

The Compton Profile was a unique and powerful technique for

investigating the electronic properties of solids, liquids and gases. For this

reason, in this study, Compton Profile measurements of FexNi1-x

alloys were carried out only on alloys with x=0.51, and there is no study

in the literature that examines the effect of change in Fe content in the alloy

on electron momentum distributions and charge transfers in detail. Therefore,

in this study, the effect of variation of Fe content on electron momentum

distributions and charge transfers in FexNi1-x (x=0.20; 0.52; 0.55; 0.58; 0.61;

and 0.64) alloys was investigated. It was found that the change in Compton

Profile values increased with decreasing Fe amount in the alloy. The part where

this change is important is the q<0.2 region where the valence electrons

cause predominantly Compton scattering.<o:p></o:p>
