Dynamical Valence Fluctuations and Magnetic Anisotropy in Sm(Co,Cu)
Alexander B. Shick, Alexander V. Andreev, Evgenia A. Tereshina-Chitrova +5
The magnetic properties of Sm-based intermetallics are governed by a delicate interplay between localized states, exchange interactions, and valence fluctuations, yet the role…
Electronic Structure of UGe Thin Films from Photoelectron Spectroscopy
Sonu George Alex, Oleksandr Romanyuk, Ivan Zorilo +7
Uranium digermanide UGe, the first ferromagnetic superconductor, represents a key composition in the U-Ge system dominated by U-5 states. To examine the impact of controlled…
Magnetic anisotropy and intermediate valence in CeCo ferromagnet
Alexander B. Shick, Evgenia A. Tereshina-Chitrova
The intermediate valence of Ce in CeCo challenges standard density functional theory (DFT) and static DFT+ approaches, which fail to capture its magnetic properties. By comb…
Comparing XMCD and DFT with STM spin excitation spectroscopy for Fe and Co adatoms on CuN/Cu(100)
M. Etzkorn, C. F. Hirjibehedin, A. Lehnert +11
We report on the magnetic properties of Fe and Co adatoms on a CuN/Cu(100)- surface investigated by x-ray magnetic dichroism measurements and density functiona…
Low temperature magnetic properties of NpNi
A. Hen, E. Colineau, R. Eloirdi +9
We present the result of an extended experimental characterization of the hexagonal intermetallic Haucke compound NpNi. By combining macroscopic and shell-specific techniques…
Antiferromagnetic I-Mn-V semiconductors
T. Jungwirth, V. Novak, X. Marti +14
After decades of research, the low Curie temperature of ferromagnetic semiconductors remains the key problem in the development of magnetic semiconductor spintronic technologies. R…
Magnetic anisotropy of single 3d spins on CuN surface
A. B. Shick, F. Máca, A. I. Lichtenstein
First-principles calculations of the magnetic anisotropy energy for Mn- and Fe-atoms on CuN/Cu(001) surface are performed making use of the torque method. The easy magnetization di…
Multiplet effects in the electronic structure of -Pu, Am and their compounds
Alexander Shick, Jindřich Kolorenč, Ladislav Havela +2
We propose a straightforward and efficient procedure to perform dynamical mean-field (DMFT) calculations on the top of the static mean-field LDA+U approximation. Starting from self…
Electron correlation effects and magnetic ordering at the Gd(0001) surface
A. B. Shick, W. E. Pickett, C. S. Fadley
Effects of electron correlation on the electronic structure and magnetic properties of the Gd(0001) surface are investigated using of the full-potential linearized augmented plane…
First principles calculation of uniaxial magnetic anisotropy and magnetostriction in strained CMR films
A. B. Shick
We performed first - principles relativistic full-potential linearized augmented plane wave calculations for strained tetragonal ferromagnetic La(Ba)MnO with an assumed experim…
