Since the discovery of the high temperature superconductivity in 1986, the research on superconducting materials undergoes a rapid development. Each year brings a discovery of new superconducting compounds. Their properties turn out to differ in many respects from those of conventional superconductors. The differences include high superconducting transition temperature, as observed in the high-Tc systems, unconventional symmetries of the superconducting order parameter, such as the d- and p-wave symmetries in cuprates and ruthenates, respectively, or the two-gap behavior in magnesium diboride. Many other superconducting and normal-state properties are also found to be unusual. In many cases, these puzzling new phenomena are not yet understood which motivates an unprecedented growth of the materials research: new theoretical models are proposed, novel experimental methods of materials studies are designed, better technological methods of preparation of the materials are developed, and new ideas of the advanced applications are tested.
The symposium will be devoted to the discussion of various newly developed aspects of superconducting materials research. Introductory talks will cover recent theoretical and experimental results in the studies of high-Tc superconductivity, which occurs in cuprate oxides, and recent investigations of the properties of other novel perovskite and non-perovskite compounds. An interesting new research area is the physics of phase transitions in vortex matter which has developed into a broad field of studies. A closely related subject is that of flux pinning, and the applicational goal is to find ways to enhance flux pinning in order to improve critical current densities. This goal can be achieved by chemical doping, radiation defects and other advanced engineering methods including grain boundary engineering, embedded nanoparticles, and processing of superconducting nanopowders. New technologies are developed to facilitate the growth of excellent quality single crystals and thin films. Their microstructural properties are tested using the nano-characterization techniques such as scanning and tunneling electron microscopies, atomic and magnetic force microscopies, and magnetooptical and Hall sensor imaging. New nanostructuring methods allow one to design and study artificially structured materials such as pinning arrays, mesoscoping superconductors, heterostructures and hybrid ferromagnetic/superconducting structures. The studies conducted on the superconducting detectors and sensors indicate possibilities of fabricating devices which are superior to those based on semiconducting materials.
