Abstract
The integrated-intensity ratio R of the Lβ and Lα lines in x-ray emission spectra of 3d transition metal oxides was measured. The magnitude of the ratio was found to depend nonmonotonically on the atomic number of the 3d elements, with a sharp rise in the middle of the series. In terms of the theory of one-electron resonant x-ray scattering in a solid, a simple relation was derived connecting this ratio with the spin polarization of occupied and empty d states. The calculated values of R qualitatively reflect the behavior of the measured I(Lβ)/I(Lα) ratio on the atomic number of 3d elements. Thus, the existence of a dependence of the integrated-intensity ratio of Lβ and Lα lines on the atomic magnetic moment has been established. All calculated R curves lie above the I(Lβ)/I(Lα)exp data, because not all factors accompanying the x-ray emission process were included in the calculation.
