Soft and chiral phonons in chiral phase of K3NiO2
Hong Dang Nguyen, Fedir Borodavka, Miroslav Lebeda +6
Raman scattering measurements confirmed the theoretical prediction that the structural phase transition from the achiral tetragonal to the chiral tetragonal phase, which occurs nea…
Dielectric, magnetic and lattice dynamics properties of double perovskite (Ca0.5Mn1.5)MnWO6
Hong Dang Nguyen, Alexei A. Belik, Petr Kužel +7
Recent dielectric and magnetic studies of (Ca0.5Mn1.5)MnWO6 ceramics [A.A. Belik, Chem. Mater. 36, 7604 (2024)] have classified this material as a rare hybrid multiferroic, with bo…
Lattice Parameters and Bulk Modulus of SrTiMnO Perovskites: A Comparison of Exchange-Correlation Functionals with Experimental Validation
Miroslav Lebeda, Jan Drahokoupil, Stanislav Kamba +4
We assessed four exchange-correlation functionals (LDA CA-PZ, GGA parametrized by PBE, PBEsol, and WC) in predicting the lattice parameters of SrTiMn$_{\mathit{x}}…
Suppression of ferromagnetism in van der Waals insulator due to pressure-induced layer stacking variation
M. Misek, U. Dutta, P. Kral +15
Ferromagnetism in van der Waals insulators like CrBr3 is highly sensitive to structural modifications. We explore the pressure-driven structural and magnetic transformations of the…
