Spin-lattice couplings in ferromagnets: analysis from first-principles
I. P. Miranda, M. Pankratova, M. Weißenhofer +8
Magnetoelasticity plays a crucial role in numerous magnetic phenomena, including magnetocalorics, magnon excitation via acoustic waves, and ultrafast demagnetization/Einstein-de Ha…
Heat-conserving three-temperature model for ultrafast demagnetization of 3d ferromagnets
M. Pankratova, I. P. Miranda, D. Thonig +6
We study the ultrafast magnetization dynamics of bcc Fe and fcc Co using the recently suggested heat-conserving three-temperature model (HC3TM), together with atomistic spin- and l…
The effect of longitudinal spin-fluctuations on high temperature properties of CoMnGe
Erna K. Delczeg-Czirjak, O. Eriksson, A. V. Ruban
It is demonstrated that thermally induced longitudinal spin fluctuations (LSF) play an important role in itinerant CoMnGe at an elevated temperature. The effect of LSF is t…
Structural and electronic properties of the random alloy ZnSeS
S. Sarkar, O. Eriksson, D. D. Sarma +1
In this article we employ density functional theory in the generalized gradient approximation to investigate the structural and electronic properties of the solid solution alloy $\…
Exchange scaling of ultrafast angular momentum transfer in 4 antiferromagnets
Y. W. Windsor, S-E. Lee, D. Zahn +11
Ultrafast manipulation of the magnetic state of matter bears great potential for future information technologies. While demagnetisation in ferromagnets is governed by dissipation o…
Inhomogeneous magnon scattering during ultrafast demagnetization
R. Knut, E. K. Delczeg-Czirjak, S. Jana +20
NiFe (Py) and Py alloyed with Cu exhibit intriguing ultrafast demagnetization behavior, where the Ni magnetic moment shows a delayed response relative to the Fe, an…
Ultrafast magnetization dynamics in pure and doped Heusler and inverse Heusler alloys
R. Chimata, E. K. Delczeg-Czirjak, J. Chico +4
By using a multiscale approach based on first-principles density functional theory combined with atomistic spin dynamics, we investigate the electronic structure and magnetization…
