Application of Hg-199 Solid-State NMR to Hg Based HTSC.
In: Physica C, 227 (3-4)
Artikel, Bibliographie
Kurzbeschreibung (Abstract)
It is proposed to study Hg-oxide ceramics, which are high-temperature superconductors, with Hg-199 NMR spectroscopy. As an exemplary application of this method first room-temperature Hg-199 spectra and spin-lattice relaxation times of samples with different macrostructure are presented. A spin-lattice relaxation time of T1 = 35 ms is found. All samples exhibit similar characteristic powder spectra caused by an axially symmetric Hg-199 spin interaction. The isotropic value and the anisotropy of the tensor relative to solid HgCl2 as a standard substance is estimated.
