Anomalous and Topological Hall Effects in Antiferromagnetic EuSn2As2 Nanostructures
Evgeny I. Maltsev, Nicolas Pérez, Romain Giraud +8
We investigate magnetotransport in exfoliated nanostructures of the candidate magnetic 3D topological insulator . Similar to macroscopic single crystals, t…
Superhydrides on the way to ambient pressure: weak localization and persistent X-ray photoconductivity in BaSiH
Dmitrii V. Semenok, Di Zhou, Sven Luther +15
Reducing the stabilization pressure of superhydrides represents one of the most important challenges in hydrogen-saturated compound chemistry. Moving in this direction, we studied…
Ferromagnetic resonance in an antiferromagnetic crystal EuSnAs
I. I. Gimazov, D. E. Zhelezniakova, R. B. Zaripov +7
We report results of electron spin resonance (ESR) measurements in single crystals of EuSnAs. In the temperature range of antiferromagnetic (AFM) ordering of Eu atoms, $T \…
Emergence of Ferromagnetism from Planar Defects in EuSn2As2 Antiferromagnet
A. Yu. Levakhova, A. L. Vasiliev, N. S. Pavlov +6
We report a study of nano-scale structural peculiarities of the antiferromagnetic layered semimetal EuSn2As2, and show that they are responsible for its puzzling magnetic propertie…
Intrinsic Negative Magnetoresistance in Layered AFM Semimetals: the Case of EuSnAs
K. S. Pervakov, A. V. Sadakov, O. A. Sobolevskiy +12
Here, by applying a comprehensive approach including magnetic, transport measurements, ARPES band structure measurements, DFT calculations, and analytical theory consideration, we…
