Observation of thermal Hall effect in diamond
Marcin Matusiak, Andrzej Ptok, Maria Szlawska +1
Numerous insulators, including non-magnetic ones, have been unexpectedly found to display a finite thermal Hall signal, which has stimulated debate about its origin. Here, we repor…
Contrasting anisotropic electron-phonon-spin coupling in FeGeTe and FeGeTe: A helicity-resolved Raman study
Smrutiranjan Mekap, Jyoti Saini, Andrzej Ptok +4
Two-dimensional van der Waals ferromagnets FeGeTe (F3GT) and FeGeTe (F5GT) exhibit pronounced magneto-optical responses, which open promising platforms for investi…
Theoretical investigation of the photovoltaic properties of MgSnN for multi-junction solar cells
Issam Mahraj, Mossab Oublal, Andrzej Ptok
The orthorhombic crystal structure of the MgSnN compound with Pna2 symmetry has been investigated as a low-cost, non-toxic material for photovoltaic (PV) applications using…
Tuning of anomalous magnetotransport properties in half-Heusler topological semimetal GdPtBi
Orest Pavlosiuk, Piotr Wiśniewski, Romain Grasset +3
Half-Heusler compounds from the PtBi family exemplify Weyl semimetals in which external magnetic field induce Weyl nodes. These materials exceptionally host topologically non-t…
Transverse and Longitudinal Magnetothermopower Promoted by Ambipolar Effect in Half-Heusler Topological Materials
Orest Pavlosiuk, Marcin Matusiak, Andrzej Ptok +2
Topologically trivial and non-trivial semimetals with a high degree of carrier compensation are well known for demonstrating large transverse magnetothermopower (). However…
Topological properties of spin block magnetic ladders in proximity of a superconductor: application to BaFeS
Shivam Yadav, Pascal Simon, Andrzej Ptok
Monoatomic chains with magnetic order in proximity of a s-wave superconductor can host Majorana edge modes. In this paper, we extend this idea to more complex spin-block chains suc…
Kagome edge states under lattice termination, spin-orbit coupling, and magnetic order
Sajid Sekh, Annica M. Black-Schaffer, Andrzej Ptok
We study the edge state properties of a two-dimensional kagome lattice using a tight-binding approach, focusing on the role of lattice termination, spin-orbit coupling, and magneti…
