Topological Hall effect in CeAlGe
M. M. Piva, J. C. Souza, G. A. Lombardi +4
The Weyl semimetal CeAlGe is a promising material to study nontrivial topologies in real and momentum space due to the presence of a topological magnetic phase. Our results at ambi…
Topological features in the ferromagnetic Weyl semimetal CeAlSi: Role of domain walls
M. M. Piva, J. C. Souza, V. Brousseau-Couture +8
In the ferromagnetic (FM) Weyl semimetal CeAlSi both space-inversion and time-reversal symmetries are broken. Our quantum oscillation (QO) data indicate that the FM ordering modifi…
Magnetic interactions of 4 electrons in the topological insulator chalcogenide BiSe
J. C. Souza, M. Carlone, G. G. Lesseux +5
The gap opening mechanism of a topological insulator, the quantum anomalous Hall effect and the axion physics are still pressing open questions and a microscopic viewpoint to furth…
Slow crystalline electric field fluctuations in the Kondo lattice SmB
M. Carlone, J. C. Souza, J. Sichelschmidt +7
This work reports on the temperature dependence of the electron spin resonance (ESR) of Gd-doped SmB single crystals at X- and Q-band microwave frequencies in differen…
Orbital localization and the role of the Fe and As orbitals in BaFeAs probed by XANES
A. G. de Figueiredo, M. R. Cantarino, W. R. da Silva Neto +9
The polarization dependence of the near edge x-ray absorption spectroscopy (XANES) is an element specific probe to the real-space distribution of the density of unoccupied states i…
Tuning the nontrivial topological properties of the Weyl semimetal CeAlSi
M. M. Piva, J. C. Souza, V. Brousseau-Couture +6
In the ferromagnetic Weyl semimetal CeAlSi both space-inversion and time-reversal symmetries are broken. We use external pressure as an effective tuning parameter and relate three…
