Irreversible properties of type II superconductors
The subjects of forces on flux lines and the connection between macroscopic force densities and individual interaction forces between single flux lines and defects are treated in some detail. A short survey is given of possible pinning mechanisms for which theoretical expressions for the maximum interaction force are derived. They can be compared with experimental data on model systems which permit the determination of the force due to a specific type of defect. Short sample data of some commercial alloys used in superconducting magnet coils are also given. A brief review of dissipative effects which may lead to thermomagnetic instabilities is given, followed by a description of experimental techniques applicable to pinning force measurements. A short outline of reversible properties is given in appendix A. Finally, appendix B contains a list of symbols and their dimensions in MKSA-units which are used throughout the book.
