The discovery of high temperature superconductors HTS
with critical temperatures Tc above the liquid
Nitrogen boiling temperature 77K, stimulated the
scientific community. Four families of HTS were
discovered. These are Yttrium, Bismuth, Thallium, and
Mercury based superconductors. Despite the extensive
research carried out after that, practical
applications faced limitations. One of the
limitations is the fact that the maximum Tc is still
far below room temperature. Various
chemical-processing methods can be used in hope to
overcome the first problem. In this book, doping with
Boron and Lithium to improve the properties of
Thallium based HTS have been studied. Another
limitation is the fact that the maximum current
carried by a HTS, namely critical current Ic, is
actually not infinite. In this regard, texturing of
superconducting grains and irradiation are very
successful methods to improve the limiting Ic. In
this work, the production of superconducting tapes
and the effect of magnetic field and gamma
irradiation on them have been studied. This book is
mostly useful for higher-grade undergraduate
students, graduate students, materials scientists,
and experimental physicists.
