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

Abstract

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 displays a strongly nonlinear field dependence which cannot be described using a standard two-band Drude model. A low-field Hall anomaly, reminiscent of the Hall response associated with “strange-metal” physics, develops at T < 1.5 K. At two characteristic magnetic fields (μ₀H₁ 1/4 19.6 T and μ₀H₂ ~ 31 T), signatures appear in the Hall coefficient, magnetic torque, and magnetoresistance; the latter characteristic field coincides with the occurrence of a change in quantum-oscillation frequency. We suggest that they are likely to be field-induced Lifshitz transitions. Moreover, above 35 T, where the most pronounced quantum oscillations are detected, the background resistivity displays anmore »« less

At two characteristic magnetic fields (μ0H1 1/4 19.6 T and μ0H2 ~ 31 T), signatures appear in the Hall coefficient, magnetic torque, and magnetoresistance; the latter characteristic field coincides with the occurrence of a change in quantum-oscillation frequency. We suggest that they are likely to be field-induced Lifshitz transitions. Moreover, above 35 T, where the most pronounced quantum oscillations are detected, the background resistivity displays an unusual, nonmetallic Tα behavior, with α being field dependent and varying between -1.5 and -2 By normalizing the Shubnikov–de Haas oscillation amplitude to this Tα dependence, the calculated cyclotron mass becomes more consistent with that deduced from de Haas–van Alphen oscillations. Our results support a novel two-fluid scenario in YbB12: A Fermi-liquid-like fluid of charge-neutral quasiparticles coexists with charge carriers that remain in a nonmetallic state. The former experience successive Lifshitz transitions and develop Landau quantization in applied magnetic fields, while scattering between both fluids allows the Shubnikov–de Haas effect to be observed in the electrical transport. The verification of this two-fluid scenario by the data in the current work strongly suggests that YbB12 represents a new phase of matter.},

Topological surface conduction in Kondo insulator YbB₁₂

Journal Article Sato, Y. ; Xiang, Ziji ; Kasahara, Y. ; ... - Journal of Physics. D, Applied Physics

Kondo insulators have recently aroused great interest because they are promising materials that host a topological insulator state caused by the strong electron interactions. Moreover, recent observations of the quantum oscillations in the insulating state of Kondo insulators have come as a great surprise. Here, we investigate the surface electronic state of a prototype Kondo insulator YbB₁₂, we measured the transport properties of single crystals and microstructures. In all samples, the temperature dependence of the electrical resistivity is insulating at high temperatures and the resistivity exhibits a plateau at low temperatures. The magnitude of the plateau value decreases with reducingmore »« less

Unusual high-field metal in a Kondo insulator

Journal Article Xiang, Ziji ; Chen, Lu ; Chen, Kuan-Wen ; ... - Nature Physics

Strong electronic interactions in condensed-matter systems often lead to unusual quantum phases. One such phase occurs in the Kondo insulator YbB12, the insulating state of which exhibits phenomena that are characteristic of metals, such as magnetic quantum oscillations, a gapless fermionic contribution to heat capacity and itinerant-fermion thermal transport. To understand these phenomena, it is informative to study their evolution as the energy gap of the Kondo insulator state is closed by a large magnetic field. Here we show that clear quantum oscillations are observed in the resulting high-field metallic state in YbB12; this is despite it possessing relatively highmore »« less

Shubnikov-de Haas quantum oscillations reveal a reconstructed Fermi surface near optimal doping in a thin film of the cuprate superconductor $\Pr_{1.86} {Ce}_{0.14} {CuO}_{4 \pm δ}$

Journal Article Breznay, Nicholas P. ; Hayes, Ian M. ; Ramshaw, B. J. ; ... - Physical Review B

We study magnetotransport properties of the electron-doped superconductor Pr2-xCexCuO4±δ with x=0.14 in magnetic fields up to 92 T, and observe Shubnikov-de Haas magnetic quantum oscillations. The oscillations display a single frequency F=255±10 T, indicating a small Fermi pocket that is ~1% of the two-dimensional Brillouin zone and consistent with a Fermi surface reconstructed from the large holelike cylinder predicted for these layered materials. Despite the low nominal doping, all electronic properties including the effective mass and Hall effect are consistent with overdoped compounds. Our study demonstrates that the exceptional chemical control afforded by high quality thin films will enable Fermimore »« less

Possible manifestations of the chiral anomaly and evidence for a magnetic field induced topological phase transition in the type-I Weyl semimetal TaAs

Journal Article Zhang, Q. R. ; Zeng, B. ; Chiu, Y. C. ; ... - Physical Review B

We studied the magnetoresistivity and the Hall effect of the type-I Weyl semimetal TaAs to address the controversy surrounding its anomalous transport properties in relation to its bulk topological character. For fields and currents along the basal plane, we observe a very pronounced planar Hall effect (PHE) upon field rotation with respect to the crystallographic axes at temperatures as high as T = 100K. Parametric plots of the PHE signal as a function of the longitudinal magnetoresistivity (LMR) collected at T = 10K lead to concentric traces as reported for Na₃Bi and GdBiPt. This would suggest that the negative LMRmore »« less
