Effects of GaAs buffer layer on quantum anomalous Hall insulator Vy(BixSb1-x)2-yTe3
Yusuke Nakazawa, Takafumi Akiho, Kiyoshi Kanisawa +3
We report the growth, structural characterization, and transport properties of the quantum anomalous Hall insulator Vy(BixSb1-x)2-yTe3 (VBST) grown on a GaAs buffer layer by molecu…
Quantum Hall effect in epitaxial graphene with permanent magnets
F. D. Parmentier, T. Cazimajou, Y. Sekine +5
We have observed the well-kown quantum Hall effect (QHE) in epitaxial graphene grown on silicon carbide (SiC) by using, for the first time, only commercial NdFeB permanent magnets…
Spatial distribution of dynamically polarized nuclear spins in electron spin domains in the fractional quantum Hall state studied by nuclear electric resonance
S. Watanabe, G. Igarashi, N. Kumada +1
Nuclear electric resonance (NER) is based on nuclear magnetic resonance mediated by spatial oscillations of electron spin domains excited by a radio frequency (RF) electric field,…
Unraveling the spin polarization of the v = 5/2 fractional quantum Hall state
Lars Tiemann, Gerardo Gamez, Norio Kumada +1
The fractional quantum Hall (FQH) effect at filling factor v = 5/2 has recently come under close scrutiny, as it may possess quasi-particle excitations obeying nonabelian statistic…
Decoherence of nuclear spins due to direct dipole-dipole interactions probed by resistively detected nuclear magnetic resonance
T. Ota, G. Yusa, N. Kumada +3
We study decoherence of nuclear spins in a GaAs quantum well structure using resistively detected nuclear magnetic resonance. The transverse decoherence time T2 of 75As nuclei is e…
