Abstract
X-ray absorption spectra from the K-edge of boron in amorphous and crystallized Fe80B20 alloys are presented. The spectra are discussed together with calculated densities of states, a possible core-exciton energy level and basic XANES phenomena. Satisfying coincidence between band structure calculations and experimental results can be recognized. The results in principle permit to decide between different models for the atomic structure of the amorphous Fe80B20 alloy. The structure model of Zweck rather approaches the present experimental data than the model of Fujiwara.
