The Structure of X-ray Emission of K?-Line in Selected Iron-Dysprosium and Iron-Yttrium Compounds

Abstract

PACS: 78.70.En Two low energy satellites of the iron K b line were observed in the spectra of DyFe 2 , DyFe 3 , Dy 2 Fe 17 , YDyFe 17 and Y 2 Fe 17 , and were interpreted as plasmon modes excited in the crystalline lattice. Peak energies were successfully fitted within the electronic collective excitation model specific to the crystal and electronic structures of related compounds.

Valence band and magnetic moment of Mn in TbMn2 and TbMn2D2 studied by Kβ5 emission X-ray spectroscopy

“…Using the same method of satellite position analysis as in our previous papers [12,13], we have obtained 2.7-2.9 magnetically uncompensated manganese electrons for TbMn 2 and TbMn 2 D 2 . Thus, Mn atoms are in rather high magnetic moment state in both samples, contrary to the value 1.2µ B obtained in [4] for particular manganese sites in TbMn 2 D 2 .…”
