      The authors cover basic properties of superconductors and discuss stability and different material groups with reference to the latest and most promising applications, devoting the last third of the book to applications in power engineering, medicine, and low temperature physics.   The book comprises six chapters which deal with the critical currents and the ferromagnetism-superconductivity coexistence in high-Tc oxides. It begins by gathering key data for superconducting state and the fundamental properties of the conventional superconductors, followed by a recap of the basic theories of :

      We present a statistical mechanical model for critical currents which is successful in describing both the in-plane and out-of-plane magnetic field angle dependence of J c. This model is constructed using the principle of maximum entropy, that is, by maximizing the information entropy of a distribution, subject to by: 5.   Generally, studies of the critical current I c are necessary if superconductors are to be of practical use, because I c sets the current limit below which there is a zero-resistance state.

    This workshop includes about papers describing the flux pinning and related electromagnetic phenomena in superconductors. Various problems are argued on exotic properties of flux lines, flux dynamics, flux pinning mechanisms, critical current.   The minimum current that can be passed in a specimen without destroying its superconductivity is called the critical current. A current produce the magnetic field when flows in .

Magnetic and electromagnetic properties of superconductors Critical field. One of the ways in which a superconductor can be forced into the normal state is by applying a magnetic weakest magnetic field that will cause this transition is called the critical field (H c) if the sample is in the form of a long, thin cylinder or ellipsoid and the field is oriented parallel to the long.

Superconductivity in Metals and Alloys. The object of this report is to explain 1) the structure sensitive factors affecting the kinetics of the transition between the normal and superconducting states of selected metals, metal alloys, and intermetallic compounds, and 2)to explore the area of intermetallic compounds and compound alloys for new superconductors.

A probe has been designed and built to measure the critical current density (J C)of short superconducting wires and tapes as a function of strain (e) in small bore high field magnets.

Any material exhibiting these properties is a an ordinary metallic conductor, whose resistance decreases gradually as its temperature is lowered even down to near absolute zero, a superconductor has a.The most important practical characteristic of a superconductor is its critical current density.

This article traces the history of the experimental discoveries and of the development of the theoretical ideas that have lead to the understanding of those factors that control critical current densities.
