Gateway to all-optical spin switching in Heusler ferrimagnets: Pancharatnam-Berry tensor and magnetic moment ratio
G. P. Zhang, Y. Q. Liu, M. S. Si +4
All-optical spin switching (AOS) is a new phenomenon found in a small group of magnetic media, where a single laser pulse can switch spins from one direction to another, without as…
Optical response of small closed-shell sodium clusters
George Pal, Georgios Lefkidis, Hans Christian Schneider +1
Absorption spectra of closed-shell Na_2, Na_3+, Na_4, Na_5+, Na_6, Na_7+, and Na_8 clusters are calculated using a recently implemented conserving linear response method. In the fr…
Optical absorption spectra of finite systems from a conserving Bethe-Salpeter equation approach
George Pal, Yaroslav Pavlyukh, Wolfgang Hübner +1
We present a method for computing optical absorption spectra by means of a Bethe-Salpeter equation approach, which is based on a conserving linear response calculation for electron…
First principles calculation of structural and magnetic properties for Fe monolayers and bilayers on W(110)
X. Qian, W. Hübner
Structure optimizations were performed for 1 and 2 monolayers (ML) of Fe on a 5 ML W(110) substrate employing the all-electron full-potential linearized augmented plane-wave (FP-LA…
Nonlinear Magneto-Optics of freestanding Fe monolayers from first principles
J. P. Dewitz, W. Hübner
The nonlinear magneto-optical Kerr-effect (NOLIMOKE) is determined for freestanding Fe monolayers with several in-plane structures from first principles. Based on the theory of non…
Femtosecond electron and spin dynamics probed by nonlinear optics
G. P. Zhang, W. Hübner
A theoretical calculation is performed for the ultrafast spin dynamics in nickel using an exact diagonalization method. The present theory mainly focuses on a situation where the i…
The origin of the 90 degree magneto-optical Kerr rotation in CeSb
U. Pustogowa, W. Hubner, K. H. Bennemann
We calculate the linear magneto-optical Kerr rotation for CeSb in the near-infrared spectral range. Using an exact formula for large Kerr rotation angles and a simplified electroni…
