Evidence for a field-induced Lifshitz transition in the Weyl semimetal CeAlSi
M. M. Piva, T. Helm, J. C. Souza +4
The Weyl semimetal CeAlSi crystallises in the noncentrosymmetric tetragonal space group and exhibits ferromagnetic order below 8 K, thereby breaking both spatial inversion…
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…
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…
