Effect of external magnetic field on valence-electron structures of Fe and Ni in Invar, Permalloy and the other Fe-Ni alloys by using Kβ-to-Kα X-ray intensity ratiosAlim, BünyaminHan, IbrahimDemir, LütfüFe-Ni alloyKβ-to-Kα X-ray intensity ratioMagnetic fieldValence electron structureThe effect of external magnetic field on the valence-electron structures of Fe and Ni in various Fe-Ni alloy compositions was investigated by using X-ray fluorescence spectroscopy. Kβ-to-Kα X-rayin-tensity ratios of Fe and Ni in Invar(Fe0.64Ni0.36), Permalloy(Fe0.20Ni0.80) and Fe N - i x 1x Firstly,(x=0, 0.40, 0.52, 0.55, 0.61, and 1) alloys were measured without any magnetic field and under 0.5 and 1 T external magnetic fields, separately. Later, the valence-electron structures of Fe and Ni in both pure form and alloys were obtained by comparison of measured X-ray intensity ratios with the results of multi-configurations Dirac-Fock (MCDF) calculations. The results obtained for valence-electron structures of Fe and Ni in various Fe-Ni alloys were evaluated in terms of magnetic field effect, delocalization and/or charge transfer phenomena. The results have shown that valence electron structure of Fe and Ni in Fe-Ni alloys are dependent on both external magnetic field and concentration of alloy elements.Elsevier Ltd2016Articlehttps://rdlopen.rawdatalibrary.net/r/bayburt/12509https://doi.org/10.1016/j.apradiso.2016.03.0010969-8043enApplied Radiation and Isotopesinfo:eu-repo/semantics/openAccessinfo:eu-repo/semantics/articlehttps://bayburt-rdlopen.rawdatalibrary.net/tr/items/bayburt/12509
