Ab-initio calculation of magnetic exchange interactions using the spin-spiral method in VASP: Self-consistent versus magnetic force theorem approaches
Umit Dogan Daglum, Maria Stamenova, Ersoy Sasioglu +1
We present an ab initio investigation of magnetic exchange interactions using the spin-spiral method implemented in the VASP code, with a comparative analysis of the self-consisten…
Chiral split magnons in metallic g-wave altermagnets: Insights from many-body perturbation theory
Wejdan Beida, Ersoy Sasioglu, Christoph Friedrich +3
Altermagnets are a novel class of magnetic materials that bridge the gap between ferromagnets (FMs) and antiferromagnets (AFMs). A key feature is the non-degeneracy of magnon modes…
