Variety of magnetic topological phases in the (MnBi $_{2}$ Te $_{4}$ )(Bi $_{2}$ Te $_{3}$ ) $_{m}$ 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…

A quantum heat engine based on dynamical materials design

G. Tulzer, M. Hoffmann, R. E. Zillich

We propose a novel type of quantum heat engine based on the ultrafast dynamical control of the magnetic properties of a nano-scale working body. The working principle relies on non…

Unique thickness-dependent properties of the van der Waals interlayer antiferromagnet $MnB i_{2} T e_{4}$ 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 Gd $_{1 - x}$ Ca $_{x}$ MnO $_{3}$

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 Gd $_{1 - x}$ Ca $_{x}$ MnO $_{3}$ (GCMO) over the full concentration range based on density f…

Tuning the probability of defect formation via substrate strains in Sr $_{2}$ FeMoO $_{6}$ films

Waheed A. Adeagbo, Martin Hoffmann, Arthur Ernst +4

Since oxide materials like Sr $_{2}$ FeMoO $_{6}$ are usually applied as thin films, we studied the effect of biaxial strain, resulting from the substrate, on the electronic and magnetic…
