Uniaxial stress tuning of the anomalous Hall effect in Mn3Ge
G. A. Lombardi, L. O. Kutelak, M. M. Piva +6
Tunable electronic properties in magnetic materials lead to novel physical phenomena that have the potential to be exploited in the design of new spintronic devices. Here, we repor…
Importance of the semimetallic state for the quantum Hall effect in HfTe
M. M. Piva, R. Wawrzyńczak, Nitesh Kumar +5
At ambient pressure, HfTe is a material at the boundary between a weak and a strong topological phase, which can be tuned by changes in its crystalline structure or by the ap…
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…
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…
Robust narrow-gap semiconducting behavior in square-net LaCdAs
Mario M. Piva, Marein C. Rahn, Sean M. Thomas +6
ABSTRACT: Narrow-gap semiconductors are sought-after materials due to their potential for long-wavelength detectors, thermoelectrics, and more recently non-trivial topology. Here w…
