NMR Evidence for Spin Canting in a Bilayer nu = 2 Quantum Hall System
N. Kumada, K. Muraki, Y. Hirayama
We investigate the electron spin states in the bilayer quantum Hall system at total Landau level filling factor nu =2 exploiting current-pumped and resistively detected NMR. The me…

Local Heavy Quasiparticle in Four-Level Kondo Model
Kazumasa Hattori, Yosuke Hirayama, Kazumasa Miyake
An impurity four-level Kondo model, in which an ion is tunneling among 4-stable points and interacting with surrounding conduction electrons, is investigated using both perturbativ…

Spin Degree of Freedom in the nu =1 Bilayer Electron System Investigated via Nuclear Spin Relaxation
N. Kumada, K. Muraki, K. Hashimoto +1
The nuclear-spin-relaxation rate 1/T_1 has been measured in a bilayer electron system at and around total Landau level filling factor nu =1. The measured 1/T_1, which probes electr…
