In this work,
EDXRF are used to demonstrate the effect of an applied magnetic field, on the
determination of energy of X-ray line, full width at half maximum (FWHM),
asymmetry index (AI) and intensity ratio values. To this end, various initial
magnetic fields were induced on a selenide compounds, and for each level of
residual magnetic field, their corresponding Kα and Kβ
spectra were collected from a Si(Li) detector. The results showed a strong correlation between the residual sample
magnetic field and the atomic parameters such as energy shifts and asymmetry
indices. It was observed that the chemical shift values increases with
applying the sample magnetic field but FWHM values starts decreasing with
higher levels of initial residual magnetic fields.
