Magnetic anisotropy energy of disordered tetragonal Fe-Co systems from ab initio alloy theory
Ilja Turek, Josef Kudrnovsky, Karel Carva
We present results of systematic fully relativistic first-principles calculations of the uniaxial magnetic anisotropy energy (MAE) of a disordered and partially ordered tetragonal…
Super-Diffusive Spin-Transport as a Mechanism of Ultrafast Demagnetization
Marco Battiato, Karel Carva, Peter M. Oppeneer
We propose a semi-classical model for femtosecond-laser induced demagnetization due to spin-polarized excited electron diffusion in the super-diffusive regime. Our approach treats…
Influence of laser-excited electron distributions on the x-ray magnetic circular dichroism spectra: Implications for femtosecond demagnetization in Ni
K. Carva, D. Legut, P. M. Oppeneer
In pump-probe experiments an intensive laser pulse creates non-equilibrium excited electron distributions in the first few hundred femtoseconds after the pulse. The influence of no…
Landauer theory of ballistic torkances in non-collinear spin valves
K. Carva, I. Turek
We present a theory of voltage-induced spin-transfer torques in ballistic non-collinear spin valves. The torkance on one ferromagnetic layer is expressed in terms of scattering coe…
