The aim of this unit is to explain the basic properties of superconductivity, and illustrate contemporary applications of related phenomena.
After taking this unit the student should be able to:
* describe the basic properties of superconductors;
* apply fundamental knowledge of superconductors to applications of superconductivity in technology and the research laboratory;
* make quantitative estimates of the parameters that govern superconductivity.
