Magnesium diboride superconductors: Development and properties
Discovered in 2001, MgB2 superconductor with the critical temperature of 39 K is one of the most promising candidates for high-current applications (magnets for magnetic resonance imaging, etc.). However, to utilize its properties, the current carrying ability of MgB2 should be enhanced. An important breakthrough is achieved by converting it into MgB2-xCx superconductor. This book describes extensive research efforts on development of MgB2- xCx superconductors and understanding their electromagnetic behaviour. Comprehensive study of microstructural and superconducting properties of MgB2 with different C-based dopants allowed us to (i) develop an advanced approach for the C-doping; (ii) classify a broad range of dopants and evaluate their effectiveness for enhancing the required properties of MgB2; (iii) identify factors affecting current-carrying ability in MgB2-xCx at high and low magnetic fields. This book should be of interest to a broad range of multidisciplinary scientists, engineers, technologists, product developers, and students dealing with MgB2 superconductor, its development, performance, and optimization for various practical applications.
