Effect of geometry on magnetism of Hund's metals: A case study with BaRuO
Hrishit Banerjee, Hermann Schnait, Markus Aichhorn +1
In order to explore the effects of structural geometry on properties of correlated metals we investigate the magnetic properties of cubic (3C) and hexagonal (4H) BaRuO. While t…
Comparing the effective enhancement of local and non-local spin-orbit couplings on honeycomb lattices due to strong electronic correlations
Markus Richter, Johannes Graspeuntner, Thomas Schäfer +2
We investigate the interplay of electronic correlations and spin-orbit coupling (SOC) for a one-band and a two-band honeycomb lattice model. The main difference between the two mod…
Temperature and Pressure-driven Spin transitions and Piezochromism in a Mn-based Hybrid Perovskite
Hrishit Banerjee, Angela Rittsteuer, Markus Aichhorn
Hybrid perovskites have been at the forefront of condensed matter research particularly in context of device applications primarily in relation to applications in the field of sola…
Importance of electronic correlations for the magnetic properties of the two-dimensional ferromagnet CoBr
Hrishit Banerjee, Markus Aichhorn
We investigate the emergence of ferromagnetism in the two-dimensional metal-halide CoBr, with a special focus on the role of electronic correlations. The calculated phonon spec…
