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…
Disorder-induced damping of spin excitations in Cr-doped BaFeAs
Marli R. Cantarino, Rafael M. P. Teixeira, R. Pakuszewski +9
In doped Hund's metals, such as the iron-based superconductors, effects like charge doping and chemical pressure are often considered the dominant factors. Partial chemical substit…
Incoherent electronic band states in Mn-substituted BaFeAs
Marli R. Cantarino, Kevin R. Pakuszewski, Björn Salzmann +8
Chemical substitution is commonly used to explore new ground states in materials, yet the role of disorder is often overlooked. In Mn-substituted BaFeAs (MnBFA), superc…
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…
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…
