Iron based superconductors have been discovered eight years ago only and have unleashed tremendous research and development activities throughout the world due to their unusual properties compared to classical and cuprate superconductors. From the point of view of applications, the huge critical magnetic field exhibited by iron-based superconductors is especially promising for very high field power devices. However, there are still plenty of open questions, which need to be answered to be able to exploit this unique potential. The aim of this work is to contribute to the knowledge of iron-based superconductors and/or perform pioneering work relating to the manufacture of long wires in view of applications in magnets, generators, fusion reactors, etc. We shall concentrate on compounds that do not contain arsenic, since the toxicity of this element precludes the large scale use of FeAs-based superconductors.  We can propose a variety of projects covering different aspects of research ranging from fundamental physics to applied technology e.g.:

-Studies of the effects of doping foreign elements on the superconducting properties.

-Development of a chemical bath deposition technology for coating long tapes.

-Manufacture and characterization of long wires by in-situ and ex-situ techniques.

-Microstructural optimization of bulk samples by use of uniaxial pressure during reaction.   

 

During this project you are going to:

-Produce FeSe-based superconductors by various techniques depending on your project.

-Conduct microstructural characterization of your samples by means of X-ray diffraction, optical and electron microscopy.

-Perform magnetization, evt. transport measurements at cryogenic temperatures under magnetic field to evaluate the superconducting performance of your samples.

-Analyze your experimental results using state of the art theoretical models.

 

Learning objectives:

At the end of this project you will be able to:

-Use various experimental characterization tools (X-ray diffraction, thermal analysis, infrared spectroscopy, electron microscopy, low temperature magnetization measurements, etc.) and explain their basic principles as well as limitations.

-Critically evaluate your results.

-Draw links between microstructure and performance.

-Perform an efficient literature search and compare your own results to published data.

-Present your results to a scientific audience under conditions equivalent to an international conference.

-Write the draft of a scientific publication.
