Stoner contributions to the magnon equation of motion
Thorbjørn Skovhus, Patrik Thunström
From linear response theory, we derive the equation of motion for Landau-damped magnon quasi-particles in absence of spin-orbit coupling. The derivation is based on a minimal set o…
Classifying magnons in itinerant ferromagnets from linear response TDDFT: Fe, Ni and Co revisited
Thorbjørn Skovhus, Thomas Olsen
The magnetic excitation spectrum of itinerant magnets exhibits rich and complex spectral features that often complicate interpretation of the underlying physics. For perturbations…
Implementation of the magnetic force theorem for large-scale calculations of magnon bands: application to yttrium iron garnet
Thorbjørn Skovhus, Varun Rajeev Pavizhakumari, Thomas Olsen
We present an efficient implementation of the magnetic force theorem which allows for direct evaluation of exchange parameters in q-space. The exchange parameters are calculated di…
Beyond the random phase approximation for calculating Curie temperatures in ferromagnets: application to Fe, Ni, Co and monolayer CrI3
Varun Rajeev Pavizhakumari, Thorbjørn Skovhus, Thomas Olsen
The magnetic properties of solids are typically analyzed in terms of Heisenberg models where the electronic structure is approximated by interacting localized spins. However, even…
Minority magnons and mode branching in monolayer FeGeTe
Thorbjørn Skovhus, Thomas Olsen
We predict the presence of minority magnons in monolayer FeGeTe using first principles calculations. Minority magnons constitute a new type of collective magnetic excitatio…
GPAW: An open Python package for electronic-structure calculations
Jens Jørgen Mortensen, Ask Hjorth Larsen, Mikael Kuisma +44
We review the GPAW open-source Python package for electronic structure calculations. GPAW is based on the projector-augmented wave method and can solve the self-consistent density…
Plane wave implementation of the magnetic force theorem for magnetic exchange constants: Application to bulk Fe, Co and Ni
Frederik Durhuus, Thorbjørn Skovhus, Thomas Olsen
We present a plane wave implementation of the magnetic force theorem, which provides a first principles framework for extracting exchange constants parameterizing a classical Heise…
Magnons in antiferromagnetic bcc-Cr and CrO from time-dependent density functional theory
Thorbjørn Skovhus, Thomas Olsen
We apply time-dependent density functional theory to calculate the transverse magnetic susceptibility of bcc-Cr and CrO, which constitute prototypical examples of antiferro…
Influence of static correlation on the magnon dynamics of an itinerant ferromagnet with competing exchange interactions -- a first principles study of MnBi
Thorbjørn Skovhus, Thomas Olsen, Henrik M. Rønnow
We present first principles calculations of the dynamic susceptibility in strained and doped ferromagnetic MnBi using time-dependent density functional theory. In spite of being a…
Atomic Simulation Recipes -- a Python framework and library for automated workflows
Morten Gjerding, Thorbjørn Skovhus, Asbjørn Rasmussen +4
The Atomic Simulation Recipes (ASR) is an open source Python framework for working with atomistic materials simulations in an efficient and sustainable way that is ideally suited f…
Dynamic transverse magnetic susceptibility in the projector augmented-wave method. Application to Fe, Ni, and Co
Thorbjørn Skovhus, Thomas Olsen
We present a first principles implementation of the dynamic transverse magnetic susceptibility in the framework of linear response time-dependent density functional theory. The dyn…
Recent Progress of the Computational 2D Materials Database (C2DB)
M. N. Gjerding, A. Taghizadeh, A. Rasmussen +13
The C2DB is a highly curated open database organizing a wealth of computed properties for more than 4000 atomically thin two-dimensional (2D) materials. Here we report on new mater…
