Correlated excited states in the narrow gap band semiconductor FeSi and antiferromagnetic screening of local spin moments
Sergii Khmelevskyi, Georg Kresse, Peter Mohn
The physical properties of the semiconductor FeSi with very narrow band gap, anomalous behavior of the magnetic susceptibility and metal-insulator transition at elevated temperatur…
Ab initio calculation of the spin lattice relaxation time for nitrogen-vacancy centers in diamond
Johannes Gugler, Thomas Astner, Andreas Angerer +3
We investigate the fundamental mechanism of spin phonon coupling in the negatively charged nitrogen vacancy center in diamond in order to calculate the spin latti…
Competing magnetic interactions in spin-1/2 square lattice: hidden order in SrVO
Bongjae Kim, Sergii Khmelevskyi, Peter Mohn +1
With decreasing temperature SrVO undergoes two structural phase transitions, tetragonal-to-orthorhombic-to-tetragonal, without long-range magnetic order. Recent experiments…
Solid-state electron spin lifetime limited by phononic vacuum modes
Thomas Astner, Johannes Gugler, Andreas Angerer +10
Longitudinal relaxation is the process by which an excited spin ensemble decays into its thermal equilibrium with the environment. In solid-state spin systems relaxation into the p…
The influence of anti-site defects and stacking faults on the magneto crystalline anisotropy of FePt
Michael Wolloch, Dieter Suess, Peter Mohn
We present density functional theory (DFT) calculations of the magnetic anisotropy energy (MAE) of FePt, which is of great interest for magnetic recording applications. Our data, a…
Impact of lattice dynamics on the phase stability of metamagnetic FeRh: Bulk and thin films
Michael Wolloch, Markus E. Gruner, Werner Keune +20
We present phonon dispersions, element-resolved vibrational density of states (VDOS) and corresponding thermodynamic properties obtained by a combination of density functional theo…
