Dynamic Nuclear Polarization in Silicon Microparticles
A. E. Dementyev, D. G. Cory, C. Ramanathan
We report record high Si-29 spin polarization obtained using dynamic nuclear polarization in microcrystalline silicon powder. Unpaired electrons in this silicon powder are due to d…
The Intrinsic Origin of Spin Echoes in Dipolar Solids Generated by Strong Pi Pulses
Dale Li, Yanqun Dong, R. G. Ramos +4
In spectroscopy, it is conventional to treat pulses much stronger than the linewidth as delta-functions. In NMR, this assumption leads to the prediction that pi pulses do not refoc…
Spectroscopic Evidence for the Localization of Skyrmions near Nu=1 as T->0
P. Khandelwal, A. E. Dementyev, N. N. Kuzma +3
Optically pumped nuclear magnetic resonance measurements of Ga-71 spectra were carried out in an n-doped GaAs/Al0.1Ga0.9As multiple quantum well sample near the integer quantum Hal…
Optically Pumped NMR Studies of Electron Spin Polarization and Dynamics: New Constraints on the Composite Fermion Description of nu = 1/2
A. E. Dementyev, N. N. Kuzma, P. Khandelwal +3
The Knight shift and the nuclear spin-lattice relaxation rate 1/T1 of Ga-71 nuclei are measured in GaAs quantum wells at Landau level filling factor nu = 1/2 using optically pumped…
