Research on Stability of Magnesium DiborideSuperconductors

Magnesium Diboride (MgB2) is a newcomer in the field of superconductors. It offers an easily attainable usage temperature around 20 K with cheap wire cost. However, the wires employ different matrix materials than superconductor engineers are used to use. These, in principle, result in reduced stability. Also, ferromagnetic components may be included, which causes peculiarities in the modelling of coil critical current. This book considers stability issues of MgB2 superconductors, while also discussing on the computation of coil critical current when a wire includes ferromagnetic matrix. A detailed outline is also given in the background of the book; electromagnetism, thermodynamics and superconductivity are discussed in a reasonable extent. Then, stability models, as well as a variety of measurement results, are presented and discussed in detail. This book gives an outstanding opportunity to familiarise oneself with the stability of superconductors and especially for modelling the related phenomena. The book works as a good guideline for both the young beginning researchers and the senior scientists with its remarkable effort on pedagogy.
