Observation of the anomalous Hall effect in a layered polar semiconductor
Seo-Jin Kim, Jihang Zhu, Mario M. Piva +10
Progress in magnetoelectric materials is hindered by apparently contradictory requirements for time-reversal symmetry broken and polar ferroelectric electronic structure in common…
Observation of an Anomalous Hall Effect in Single-crystal Mn3Pt
Belen E. Zuniga-Cespedes, Kaustuv Manna, Hilary M. L. Noad +5
The Mn3X family of compounds was the first in which a large anomalous Hall effect (AHE) was predicted to arise from a purely antiferromagnetic structure, due to the Berry curvature…
Bonding and Electronic Nature of the Anionic Framework in LaPdS
Tanya Berry, Michael Nicklas, Qun Yang +6
Double Dirac materials are a topological phase of matter in which a non-symmorphic symmetry enforces greater electronic degeneracy than normally expected up to eightfold. The cubic…
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…
Improved magnetostructural and magnetocaloric reversibility in magnetic Ni-Mn-In shape-memory Heusler alloy by optimizing the geometric compatibility condition
P. Devi, C. Salazar Mejia, M. Ghorbani Zavareh +6
We report an improved reversibility of magnetostriction and inverse magnetocaloric effect (MCE) for the magnetic shape-memory Heusler alloy NiMnIn. We show…
Reversible adiabatic temperature change in the shape memory Heusler alloy Ni2.2Mn0.8Ga: An effect of structural compatibility
P. Devi, M. Ghorbani Zavareh, C. Salazar Mejia +5
The large magnetocaloric effect (MCE) observed in Ni-Mn based shape-memory Heusler alloys put them forward to use in magnetic refrigeration technology. It is associated with a firs…
