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…
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…
Training-induced inversion of spontaneous exchange bias field on La1.5Ca0.5CoMnO6
L. Bufaical, R. Finkler, L. T. Coutrim +5
In this work we report the synthesis and structural, electronic and magnetic properties of La1.5Ca0.5CoMnO6 double-perovskite. This is a re-entrant spin cluster material which exhi…
Critical Field Determination in Organic Antiferromagnet F4BImNN
Cris Adriano, Rafael S. Freitas, Armando Paduan-Filho +3
A combination of magnetic heat capacity measurements versus temperature under multiple fixed external fields using a polycrystalline sample, plus easy and hard axis aligned magneti…
Synthesis, characterization and ageing of MgB2
A. Serquis, R. Schulze, Y. T. Zhu +7
We studied the influence of sample preparation and defects in the superconducting properties samples using atomic ratios of Mg:B=1:1 and Mg:B=1:2. Samples were characterized by SEM…
