Chemical disorder effects on the Gilbert damping of FeCo alloys
Zhiwei Lu, I. P. Miranda, Simon Streib +8
The impact of the local chemical environment on the Gilbert damping in the binary alloy FeCo is investigated, using computations based on density functional theory.…
Coupled spin-lattice dynamics from the tight-binding electronic structure
Ramon Cardias, Simon Streib, Zhiwei Lu +7
We developed a method which performs the coupled adiabatic spin and lattice dynamics based on the tight-binding electronic structure model, where the intrinsic magnetic field and i…
Adiabatic magnon spectra with and without constraining field: Benchmark against an exact magnon spectrum
Simon Streib, Ramon Cardias, Manuel Pereiro +5
The spectrum of magnon excitations in magnetic materials can be obtained exactly from the transverse dynamic magnetic susceptibility, which is however in practice numerically expen…
Influence of non-local damping on magnon properties of ferromagnets
Zhiwei Lu, I. P. Miranda, Simon Streib +6
We study the influence of non-local damping on magnon properties of Fe, Co, Ni and FeCo () alloys. The Gilbert damping parameter is typically considered…
Adiabatic spin dynamics and effective exchange interactions from constrained tight-binding electronic structure theory: Beyond the Heisenberg regime
Simon Streib, Ramon Cardias, Manuel Pereiro +6
We consider an implementation of the adiabatic spin dynamics approach in a tight-binding description of the electronic structure. The adiabatic approximation for spin-degrees of fr…
Exchange constants for local spin Hamiltonians from tight-binding models
Simon Streib, Attila Szilva, Vladislav Borisov +7
We consider the mapping of tight-binding electronic structure theory to a local spin Hamiltonian, based on the adiabatic approximation for spin degrees of freedom in itinerant-elec…
