We report the acquisition of solid-state NMR spectra of quadrupolar nuclei obtained at very high magnetic fields (25 and 40 T), thus improving spectral sensitivity and resolution. For an example compound, the MAS spectrum obtained at 40 T is nearly free from the second-order quadrupolar broadening and can be interpreted quantitatively in a very simple manner.
The effect of Cooperons on metal-insulator transitions (MIT) in disordered interacting electronic systems is studied. It is argued that previous results which concluded that Cooperons are qualitatively unimportant near the MIT might not be correct, and that the problem is much more complicated than had previously been realized. Although we do not completely solve the Cooperon problem, we propos...
We present a 2D NMR investigation of the gapped spin-1/2 compound Cu2(C5H10N2D2)2Cl4. Our measurements reveal the presence of a magnetic field-induced transverse staggered magnetization (TSM) which persists well below and above the field-induced 3D long-range magnetically ordered (FIMO) phase. The symmetry of this TSM is different from that of the TSM induced by the order parameter of the FIMO ...
