Course content

This course introduces a comprehensive state-of-the-art of various aspects of processing methods, properties, and applications of high-Tc superconductors. For high quality materials for industrial applications, the students will have to learn and evaluate phase diagrams. Further, the students will learn to create nano-structures in the production stage and to understand the vortex pinning techniques needed for individual industrial applications. This course is designed to be as broad and rigorous as possible to cover from fundamentals to applications of high-Tc superconductors.

Purpose of class

To develop in our student’s excellence in understanding the bulk high Tc superconductor processing methods and to activate ability to produce top superconducting materials for industrial applications. The class will focus on understanding the phase diagrams, molding the new materials, to create nano-structures improving the material’s performance, especially above liquid nitrogen temperature, up to liquid oxygen temperature.

Goals and objectives

The students will be able to comprehend complex concepts, e.g. phase diagrams of high-Tc superconducting materials.
The students will be able to synthesize HTSC materials towards the creation of nano-structures, characterization and flux pinning.
The students will critically understand the batch production of single grain RE-123, especially cost efficiency way.
The students will further expand analytical acumen through microstructure analysis (SEM, AFM, TEM, STM) of nano structured RE-123.
The students will understand nano-structure creation during material processing and design of superconducting super-magnets for MagLav, MRI, DDS and other important applications.
