A Fully Relativistic Description of Spin-Resolved Auger Emission Spectroscopy — •J. Minàr, V. Popescu, and H. Ebert — Institut f"ur Physikalische Chemie, Universität M"unchen,Theresienstr. 37, 80333 München

We present a theoretical description of the spin-resolved Auger emission spectroscopy (SR-AES) that has been setup within the framework of relativistic multiple scattering theory, on the basis of Dirac equation for spin-polarized, magnetic solids.

This approach allows one to investigate the core-core-core (CCC), the core-core-valence (CCV) as well as the core-valence-valence (CVV) SR-AES for paramagnetic and ferromagnetic transition metal systems. Several corresponding applications for the CVV-case are presented and compared with previous theoretical work and available experimental data.
