Abstract

We have studied the effect of structural disorder on the de Haas van Alphen and Shubnikov de Haas quantum oscillations measured in natural, Kish, and highly oriented pyrolytic graphite samples at temperatures down to 30 mK and at magnetic fields up to 14 T. The measurements were performed on different samples characterized by means of x-ray diffractometry, transmission electron microscopy, and atomic-force microscopy techniques. Our results reveal a correlation between the amplitude of quantum oscillations and the sample surface roughness.

Hall Anomaly, Quantum Oscillations and Possible Lifshitz Transitions in Kondo Insulator ${YbB}_{12}$ : Evidence for Unconventional Charge Transport

Journal Article Xiang, Ziji; Chen, Kuan-Wen; Chen, Lu; ... - Physical Review. X

In correlated electronic systems, strong interactions and the interplay between different degrees of freedom may give rise to anomalous charge-transport properties, which can be tuned by external parameters like temperature and magnetic field. Recently, magnetic quantum oscillations and metallic low- temperature thermal conductivity have been observed in the Kondo insulator YbB₁₂, whose resistivity is a few orders of magnitude higher than those of conventional metals. As yet, these unusual observations are not fully understood. Here we present a detailed investigation of the behavior of YbB₁₂ under intense magnetic fields using both transport and torque magnetometry measurements. The Hall resistivity displaysmore »« less

Anomalous quantum oscillations and evidence for a non-trivial Berry phase in SmSb

Journal Article Wu, Fan; Guo, Chunyu; Smidman, Michael; ... - npj Quantum Materials

Topologically non-trivial electronic structures can give rise to a range of unusual physical phenomena, and the interplay of band topology with other effects such as electronic correlations and magnetism requires further exploration. The rare earth monopnictides X(Sb,Bi) (X = lanthanide) are a large family of semimetals where these different effects may be tuned by the substitution of rare-earth elements. Here we observe anomalous behavior in the quantum oscillations of one member of this family, antiferromagnetic SmSb. The analysis of Shubnikov-de Haas (SdH) oscillations provides evidence for a non-zero Berry phase, indicating a non-trivial topology of the α-band. Furthermore, striking differencesmore »« less

Quasi-two-dimensional spin-split Fermi-liquid behavior of {kappa}-(BEDT-TTF){sub 2}I{sub 3} in strong magnetic fields

Journal Article Harrison, N; Mielke, C; Rickel, D; ... - Physical Review, B: Condensed Matter

Measurements of both the magnetization and magnetotransport of {kappa}-(BEDT-TTF){sub 2}I{sub 3} (BEDT-TTF is bisethylenedithio-tetrathiafulvalene) in magnetic fields extending to 60 T at 0.4 K and 20 T at 35 mK are reported. Strong eddy currents observed in the magnetization are found to exhibit critical currentlike behavior. This might be connected with the breakdown of the quantum Hall effect, as proposed previously for {alpha}-phase salts. The strong two dimensionality leads to an apparent fall of the effective mass together with an overall suppression of the amplitude of the magnetic quantum oscillations at high magnetic fields or very low temperatures. These effectsmore »« less

Zeeman effect of the topological surface states revealed by quantum oscillations up to 91 Tesla

Journal Article Zhang, Zuocheng; Wei, Wei; Yang, Fangyuan; ... - Physical Review. B, Condensed Matter and Materials Physics

In this paper, we report quantum oscillation studies on the Bi₂Te_3-xS_x topological insulator single crystals in pulsed magnetic fields up to 91 T. For the x = 0.4 sample with the lowest bulk carrier density, the surface and bulk quantum oscillations can be disentangled by combined Shubnikov–de Haas and de Hass–van Alphen oscillations, as well as quantum oscillations in nanometer-thick peeled crystals. At high magnetic fields beyond the bulk quantum limit, our results suggest that the zeroth Landau level of topological surface states is shifted due to the Zeeman effect. The g factor of the topological surface states is estimatedmore »« less

Spin-zero anomaly in the magnetic quantum oscillations of a two-dimensional metal.

Journal Article Wosnitza, J; Gvozdikov, V; Hagel, J; ... - NJP

We report on an anomalous behavior of the spin-splitting zeros in the de Haas-van Alphen (dHvA) signal of a quasi-two-dimensional organic superconductor. The zeros as well as the angular dependence of the amplitude of the second harmonic deviate remarkably from the standard Lifshitz-Kosevich (LK) prediction. In contrast, the angular dependence of the fundamental dHvA amplitude as well as the spin-splitting zeros of the Shubnikov-de Haas (SdH) signal follow the LK theory. We can explain this behavior of the dHvA signal by small chemical-potential (CP) oscillations and find a very good agreement between theory and experiment. A detailed wave-shape analysis ofmore »« less
