Superconductivity has been found in a wide range of materials, including pure metals, alloys, compounds, oxides, and organic materials. Providing information on the basic principles, this article discusses the theoretical background, types of superconductors, and critical parameters of superconductivity Elementary properties of superconductors. Most of the physical properties of superconductors vary from material to material, such as the heat capacity and the critical temperature at which superconductivity is destroyed. On the other hand, there is a class of properties that are independent of the underlying material [en] The introduction of silver in the intergranular space of YBa 2 Cu 3 O 7 ceramics improves their normal state electrical and mechanical properties. The authors report here a study of such composites of which the grain size was found to increase with the annealing temperature, and goes through a maximum around 20% wt. silver for a constant annealing temperature (1000 degrees C)

Ternary metal hydrides play an essential role in the search for conventional high-temperature superconductors because they can be synthesized under mild conditions and recovered at ambient pressure. It has been widely accepted that the electronic structure, metallization pressure, and superconducting behavior of binary hydrides can be adjusted. The superconducting properties of FeSe depend critically on the stoichiometry . They can also be changed by different substitutions on the cation and anion sites. For example, substitution of Fe by transition metals such as Ti, V, Co, Ni and Cr destroys superconductivity [10, 11] Superconductors Materials, Properties and Applications. The book includes 17 chapters written by noted scientists and young researchers and dealing with various aspects of superconductivity, both theoretical and experimental. Topics covered includes: Field-Induced Superconductors, X-Ray Spectroscopy Studies of Iron Chalcogenides, Defect. A method of calculating the response of superconductors to weak electromagnetic fields is -formulated. The response is generated from a single-particle Green's function, defined in the presence of an electromagnetic perturbation, that satisfies the conditions imposed by gauge invariance and charge conservation. The response function is thus itself explicitly gauge invariant and charge.

Apart from the basic property of vanishing resistance below a critical temperature, T^, a wide range of superconducting behavior has been observed, and a wealth of experimental behavior has been accumulated (2,3). As experiments became better defined, a striking regularity appeared in the behavior of different superconductors Changing the ion-beam current or the volume per dose can change the superconducting properties of the resulting W strips. The sample W strips were connected to large Pt contact pads, which serve.
