Topological magnetic materials of the (MnSbTe)(SbTe) van der Waals compounds family
S. V. Eremeev, I. P. Rusinov, Yu. M. Koroteev +6
Combining robust magnetism, strong spin-orbit coupling and unique thickness-dependent properties of van der Waals crystals could enable new spintronics applications. Here, using de…
Variety of magnetic topological phases in the (MnBiTe)(BiTe) family
I. I. Klimovskikh, M. M. Otrokov, D. Estyunin +23
Quantum states of matter combining non-trivial topology and magnetism attract a lot of attention nowadays; the special focus is on magnetic topological insulators (MTIs) featuring…
Unique thickness-dependent properties of the van der Waals interlayer antiferromagnet films
Mikhail M. Otrokov, Igor P. Rusinov, María Blanco-Rey +7
Using density functional theory and Monte Carlo calculations, we study the thickness dependence of the magnetic and electronic properties of a van der Waals interlayer antiferromag…
First-principles investigations of the magnetic phase diagram of GdCaMnO
Hichem Ben Hamed, Martin Hoffmann, Waheed A. Adeagbo +5
We studied for the first time the magnetic phase diagram of the rare-earth manganites series GdCaMnO (GCMO) over the full concentration range based on density f…
Prediction and observation of the first antiferromagnetic topological insulator
Mikhail M. Otrokov, Ilya I. Klimovskikh, Hendrik Bentmann +41
Magnetic topological insulators (MTIs) are narrow gap semiconductor materials that combine non-trivial band topology and magnetic order. Unlike their nonmagnetic counterparts, MTIs…
Tuning the probability of defect formation via substrate strains in SrFeMoO films
Waheed A. Adeagbo, Martin Hoffmann, Arthur Ernst +4
Since oxide materials like SrFeMoO are usually applied as thin films, we studied the effect of biaxial strain, resulting from the substrate, on the electronic and magnetic…
Variation of magnetic properties of SrFeMoO due to oxygen vacancies
Martin Hoffmann, Victor N. Antonov, Lev V. Bekenov +3
Oxygen vacancies can be of utmost importance for improving or deteriorating physical properties of oxide materials. Here, we studied from first-principles the electronic and magnet…
Magnetic properties of defect-free and oxygen-deficient cubic SrCoO
Martin Hoffmann, Vladislav S. Borisov, Sergey Ostanin +3
We investigated theoretically electronic and magnetic properties of the perovskite material SrCoO with using a projector-augmented plane-wave method and a Gree…
Increased magnetocrystalline anisotropy in epitaxial Fe-Co-C thin films with spontaneous strain
Ludwig Reichel, George Giannopoulos, Sandra Kauffmann-Weiss +8
Rare earth free alloys are in focus of permanent magnet research since the accessibility of the elements needed for nowadays conventional magnets is limited. Tetragonally strained…
