TUTORIAL

FT S: ADVANCES IN SUPERCONDUCTIVITY
Sunday, December 1, 2002
1:00 p.m. - 4:00 p.m.
Room 206 (Hynes)

 

Superconductors form a unique class of materials with applications in detector and switching electronics, and large electrical systems utilizing the capability of loss-less current transport (wires, etc.). The tutorial will focus on two material classes under extensive research and development today: the high-temperature superconductor (HTS) copper oxides and the recently identified superconductor MgB$_2$ (T$_c$=39 K). Topics will include lattice structures and crystal chemistry of the HTS copper oxides, uniqueness and similarities with other perovskites such as the manganites, relation between structure and properties, synthesis, and modification. Progress in MgB$_2$ materials research has been extremely fast since the discovery of its superconducting properties a year and a half ago. Physical and chemical properties will be reviewed, as well as pathways to emerging applications. Topics will range from the fundamental mechanism that causes superconductivity in MgB$_2$ to the performance of practical conductor materials.
