    Spin-lattice relaxation of 113Cd and 19F nuclear spins in the crystal lattice of CdF2 semiconductor crystals with DX centers

    Temperature dependences of spin-lattice relaxation rates of the 113Cd and 19F lattice nuclei in the CdF2 semiconductor crystals containing bistable In and Ga impurity centers show that the relaxation mechanisms i...

    Nuclear Resonance Studies of YBa2Cu3O7-δ

    The copper oxide high-Tc superconductors [1–3] have proven to be a rich and challenging arena of investigation for many condensed matter experimentalists, and particularly so for nuclear resonance investigators. ...

    63,65Cu NMR and NQR in YBa2Cu3O7-δ

    NMR and NQR results are reported for 63,65Cu in YBa2Cu3O7-δ. Analysis of the high-field NMR spectrum indicates substantial disorder in the copper-oxygen planes. Nuclear relaxation rates are significantly differen...

    Interaction Effects in Liquids with Low Electron Densities

    It is a familiar fact that electrons in most elemental liquid metals and many liquid alloys behave as if they are nearly free. This is a consequence of the high conduction electron densities in these systems a...

    Metal-Metal Salt Solutions

    Recent developments in the study of metal-metal salt solutions are described with special emphasis on solutions of alkali metals and bismuth with their respective molten halides. Electron localization in ionic...

    Localization and the Metal-Nonmetal Transition in Liquids

    In 1966 Mott introduced the idea of a “pseudogap” or minimum in the electronic density of states of a disordered system.l When the pseudogap becomes sufficiently deep, he argued, a metal-nonmetal transition shoul...

    The metal-nonmetal transition in ionic liquids

    The metal-nonmetal transition in ionic liquids is reviewed with special emphasis on alkali metal-alkali halide solutions and the ionic alloy Cs-Au. Magnetic measurements, especially nuclear magnetic resonance,...
