Abstract： The X-ray K absorption spectra of iron in metglas Fe_80_B_20_ and Fe_80_Si_6_B_14_ are measured, using the rotating anode X-ray generator and the EXAFS spectrometer with bend crystal. The structural parameters of near neighbor of these metglases are determined by EXAFS. Besides, their XANES are also measured. While comparing the XANES of iron inmetglases with that in a-Fe, FeB andFe_2_B, we discovered some changes on the energies of their absorption edge and the characters of “white line” These show that there is stronger interaction between near neighboring atoms Fe-B, Fe-Si and Fe-Fe in metglases than that in the stable compounds of iron and boron. And this has an important effect on the shortrange order structure of these metglases.
