Atomic absorption background of Ba in EXAFS analysis of BaFe₁₂O₁₉ nanoparticles

J. Padeznik Gomilsek, A. Kodre, I. Arcon, S. de Panfilis and D. Makovec

An approximate Ba L₃ atomic background, exhibiting a prominent 2p4d resonance, is extracted from the L subshell EXAFS spectra of hydrated Ba²⁺ ions. The application of the background to weak L₃ EXAFS spectra of Ba hexaferrite nanoparticles is analyzed.

Keywords: X-ray absorption; hydrated barium ion L₃-edge EXAFS; Ba L₃ atomic absorption background; Ba hexaferrite nanoparticle EXAFS; [2p4d] resonant multi-electron excitation; analytical approximation to atomic background.
