Fragile altermagnetism and orbital disorder in Mott insulator LaTiO
I. V. Maznichenko, A. Ernst, D. Maryenko +5
Based on ab initio calculations, we demonstrate that a Mott insulator LaTiO (LTO), not inspected previously as an altermagnetic material, shows the characteristic features of a…
Electronic correlations arising from anti-Stoner spin excitations: an ab initio study of itinerant ferro- and antiferromagnet
S. Paischer, D. Eilmsteiner, M. I. Katsnelson +2
The anti-Stoner excitations are a spin-flips in which, effectively, an electron is promoted from a minority to a majority spin state, i.e., complementary to Stoner excitations and…
Emerging two-dimensional conductivity at Mott-band insulator interface
I. V. Maznichenko, S. Ostanin, D. Maryenko +6
Intriguingly conducting perovskite interfaces between ordinary band insulators are widely explored, whereas similar interfaces with Mott insulators are still not quite understood.…
Correlations, disorder, and multi-magnon processes in terahertz spin dynamics of magnetic nanostructures: A first-principles investigation
S. Paischer, D. Eilmsteiner, I. Maznichenko +4
Understanding the profound impact of correlation effects and crystal imperfections is essential for an accurate description of solids. Here we study the role of correlation, disord…
Non-local correlation effects due to virtual spin-flip processes in itinerant electron ferromagnets
S. Paischer, G. Vignale, M. I. Katsnelson +2
We present an ab initio method for eletcronic structure calculations, which accounts for the interaction of electrons and magnons in ferromagnets. While it is based on a many body…
Nonlinear Decay of Quantum Confined Magnons in Itinerant Ferromagnets
Kh. Zakeri, A. Hjelt, I. V. Maznichenko +2
Quantum confinement leads to the emergence of several magnon modes in ultrathin layered magnetic structures. We probe the lifetime of these quantum confined modes in a model system…
