An additional small background correction of about 2/o was made to account for Compton scattering from a Lucite source holder. This correction could be estimated only approximately which increased the uncertainty in the absolute areas but had a negligible effect on the absorption-area ratios. S. Goldsztaub, Compt.

Time-reversal of cross-polarization in nuclear magnetic resonance
It is demonstrated that the time evolution of the heteronuclear polarization-transfer process in a dipolar-coupled nuclear spin system can be reversed, leading to the observation of cross-polarization echoes. The cross-polarization echoes are induced by consecutive application of two pulse trains that produce effective Hamiltonians that differ only in sign. Cross-polarization echoes have been r...
متن کاملUnconventional symmetries of Fermi liquid and Cooper pairing properties with electric and magnetic dipolar fermions.
The rapid experimental progress of ultra-cold dipolar fermions opens up a whole new opportunity to investigate novel many-body physics of fermions. In this article, we review theoretical studies of the Fermi liquid theory and Cooper pairing instabilities of both electric and magnetic dipolar fermionic systems from the perspective of unconventional symmetries. When the electric dipole moments ar...
متن کاملCurrent Driven Magnetic Damping in Dipolar-Coupled Spin System
Magnetic damping of the spin, the decay rate from the initial spin state to the final state, can be controlled by the spin transfer torque. Such an active control of damping has given birth to novel phenomena like the current-driven magnetization reversal and the steady spin precession. The spintronic devices based on such phenomena generally consist of two separate spin layers, i.e., free and ...
متن کاملNuclear magnetic resonance polarization and coherence echoes in static and rotating solids
The mechanisms of defocusing and refocusing of spin order in extended dipolar coupled nuclear spin systems are investigated by experiments on static and on rotating solids. It is demonstrated that polarization or coherence echoes are possible also under magic-angle sample spinning. The dipolar interactions, averaged by the spinning, are recovered by rotor-synchronized multiple-pulse sequences. ...
متن کاملRelaxation Enhancement by Longitudinal Multispin Orders
Introduction: There is a great interest in increasing the longitudinal relaxation of nuclear spins for hyperpolarized imaging experiments. Longitudinal multispin orders (LOMO) correspond to the non-equilibrium population distribution and can be created in spin systems that exhibit J couplings, dipolar couplings or quadrupolar couplings (1). It can also be created via cross-correlated relaxation...
