Wigner solids of domain wall skyrmions
Kaifeng Yang, Katsumi Nagase, Yoshiro Hirayama +3
Detection and characterization of a different type of topological excitations, namely the domain wall (DW) skyrmion, has received increasing attention because the DW is ubiquitous…
Pump-probe nuclear spin relaxation study of the quantum Hall ferromagnet at filling factor nu = 2
K. F. Yang, M. M. Uddin, K. Nagase +5
The nuclear spin-lattice relaxation time T1 of the nu = 2 quantum Hall ferromagnet (QHF) formed in a gate-controlled InSb two-dimensional electron gas has been characterized using…
Probing strain modulation in a gate-defined one dimensional electron system
M. H. Fauzi, M. F. Sahdan, M. Takahashi +5
Gate patterning on semiconductors is routinely used to electrostatically restrict electron movement into reduced dimensions. At cryogenic temperatures, where most studies are carri…
Dynamic nuclear polarization at high Landau levels in a quantum point contact
M. H. Fauzi, A. Noorhidayati, M. F. Sahdan +3
We demonstrate a way to polarize and detect nuclear spin in a gate-defined quantum point contact operating at high Landau levels. Resistively-detected Nuclear Magnetic Resonance (R…
Role of chiral quantum Hall edge states in nuclear spin polarization
K. F. Yang, K. Nagase, Y. Hirayama +3
Resistively detected NMR (RDNMR) based on dynamic nuclear polarization (DNP) in a quantum Hall ferromagnet (QHF) is a highly-sensitive method for the discovery of fascinating quant…
Resistively-detected NMR lineshapes in a quasi-one dimensional electron system
M. H. Fauzi, A. Singha, M. F. Sahdan +5
We observe variation in the resistively-detected nuclear magnetic resonance (RDNMR) lineshapes in quantum Hall breakdown. The breakdown is locally occurred in a gate-defined quantu…
