I have been a Research Associate in the Bulk Superconductivity Group, part of Division C (Mechanics, Materials and Design) since October, 2018. I have been a Research Associate at different universities including the University of Frankfurt, Germany and Durham University, UK. The focus of my previous research work was on exotic magnetic systems at low-temperatures and applied superconductivity. I have studied the unusual properties of magnetic spin systems at temperatures below 50 mK and at applied magnetic fields above 35 T. I have also investigated the strain dependence of the critical current of low-temperature superconducting strands and properties of resistive joints between high-temperature superconducting tapes for nuclear fusion applications.
Research
My current research interests are in high-temperature superconductivity. In our group we are now developing a portable pulsed field magnetization (PFM) station for magnetizing bulk high-temperature superconductors (HTS) to produce high-field permanent magnets. High-field permanent magnets would provide substantial improvement in various engineering applications such as magnetron sputtering apparatus, portable MRI systems and superconducting motors. The PFM station in our group consists of a Stirling cryocooler that does not require a compressor, making the PFM station highly mobile. This table-top station can be operated with a solenoid or a split coil at temperatures down to 40 K. We are applying this PFM station to investigate the major factors which could significantly affect the final trapped field in bulk HTS. Our goal is to gain a thorough understanding of the flux dynamics during the magnetizing process so that we can predict optimal conditions for the PFM station to produce high trapped field in different bulk HTS at low operation electrical power for various applications.
