Journal ArticleDOI
Magnetotransport study of the canted antiferromagnetic phase in bilayer ν = 2 quantum Hall state
Akira Fukuda,Anju Sawada,S. Kozumi,Daiju Terasawa,Y. Shimoda,Zyun F. Ezawa,N. Kumada,Yoshiro Hirayama +7 more
TL;DR: In this paper, the authors investigated magnetotransport properties in the bilayer quantum Hall state at the total filling factor of the total electron density and the density difference between the two layers, and demonstrated the emergence of the canted antiferromagnetic (CAF) phase between the ferromagnetic phase and the spin-singlet phase.
Journal ArticleDOI
The second order recombination and spin-exchange relaxation of atomic deuterium at low temperatures in a low magnetic field
TL;DR: In this paper, the 2nd order recombination rates and spin-exchange relaxation of atomic deuterium (D) in a4He coated sample cell, using the hyperfine resonance of β(F = 1/2, mF = −1/2) − δ (F = 3/2), mF= −1 /2) transition in a low magnetic field (3.9 mT) at temperatures between 0.6 K and 1.2 K.
Journal ArticleDOI
Pseudospin Soliton in the ν = 1 Bilayer Quantum Hall State
Akira Fukuda,Daiju Terasawa,M. Morino,K. Iwata,S. Kozumi,Norio Kumada,Yoshiro Hirayama,Yoshiro Hirayama,Zyun F. Ezawa,Anju Sawada +9 more
TL;DR: In this article, the authors investigated the domain structure of pseudospins, a soliton lattice in the bilayer quantum Hall state at total Landau level filling factor (L 1 ) in a tilted magnetic field, where the pseudospin represents the layer degree of freedom.
Journal ArticleDOI
Relationship between conductance fluctuation and weak localization in graphene
TL;DR: The relationship between the universal conductance fluctuation and the weak localization effect in monolayer graphene is investigated in this article, where the authors find that the ratio of the elastic intervalley scattering time to the inelastic dephasing time varies in accordance with the conductance fluctuations.
Journal ArticleDOI
