Abstract :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.
