Electron-electron interaction strength in ferromagnetic nickel determined by spin-polarized positron annihilation
Hubert Ceeh, Josef-Andreas Weber, Peter Böni +7
The two-photon momentum distribution of annihilating electron-positron pairs in ferromagnetic nickel (Ni) was determined by measuring the spin-polarized two-dimensional angular cor…
Identifying the electronic character and role of the Mn states in the valence band of (Ga,Mn)As
J. Fujii, B. R. Salles, M. Sperl +21
We report high-resolution hard x-ray photoemission spectroscopy results on (Ga,Mn)As films as a function of Mn doping. Supported by theoretical calculations we identify, over the e…
Many-body effects in x-ray absorption and magnetic circular dichroism spectra within the LSDA+DMFT framework
O. Sipr, J. Minar, A. Scherz +2
The theoretical description of photoemission spectra of transition metals was greatly improved recently by accounting for the correlations between the d electrons within the local…
Electron correlations in CoMnFeSi Heusler compounds
S Chadov, G. H. Fecher, C. Felser +3
This study presents the effect of local electronic correlations on the Heusler compounds CoMnFeSi as a function of the concentration . The analysis has been perf…
Correlation effects in total energy of transition metals and related properties
I. Di Marco, J. Minár, S. Chadov +3
We present an accurate implementation of total energy calculations into the local density approximation plus dynamical mean-field theory (LDA+DMFT) method. The electronic structure…
