Lattice dynamics of altermagnetic ruthenium oxide RuO
Surajit Basak, Andrzej Ptok
Altermagnetic ruthenium oxide RuO crystallizes with P4/mnm symmetry. Here we discuss the lattice dynamics of this structure. We show and discuss the phonon dispersion a…
Electronic and dynamical properties of cobalt monogermanide CoGe phases under pressure
Surajit Basak, Aksel Kobiałka, Małgorzata Sternik +5
We present the pressure dependence of the electronic and dynamical properties of six different CoGe phases: orthorhombic Cmmm, hexagonal P6/mmm and P2m, monoclinic C2/m, c…
Lattice dynamics study of electron-correlation-induced charge density wave in antiferromagnetic kagome metal FeGe
Andrzej Ptok, Surajit Basak, Aksel Kobiałka +5
Electron-correlation-driven phonon soft modes have been recently reported in the antiferromagnetic kagome FeGe compound and associated with the observed charge density wave (CDW).…
Tuning the topological character of half-Heusler systems: A comparative study on YBi ( = Pd, Pt)
J. C. Souza, M. V. Ale Crivillero, H. Dawczak-Dębicki +3
Half-Heusler systems host a plethora of different ground states, especially with non-trivial topology. However, there is still a lack of spectroscopic insight into the correspondin…
Phononic drumhead surface state in distorted kagome compound RhPb
Andrzej Ptok, William R. Meier, Aksel Kobiałka +9
RhPb was initially recognized as one of a CoSn-like compounds with symmetry, containing an ideal kagome lattice of -block atoms. However, theoretical calculations predi…
Superexchange Interaction in Insulating EuZnP
Karan Singh, Shovan Dan, A. Ptok +4
We report magnetic and transport properties of single-crystalline EuZnP, which has trigonal CaAlSi-type crystal structure and orders antiferromagnetically at $\…
