Research:

I am an experimental physicist interested in understanding the pinning mechanism in high-temperature superconductors and developing devices based on superconductivity.  During my doctoral research, I worked on developing a prototype of a smart superconducting fault current limiter(SFCL). We have also tried to understand the pinning landscape in bulk polycrystalline Bi_2Sr_2Ca_2Cu_3O_10 (Bi-2223) through current density mapping. The current density mapping of the superconductor in SFCL is done by placing an array of Hall sensors around the superconductor. I have also studied pinning crossover in Bi-2223 from temperature and field dependence of local-magnetization measurements with differential magneto-optical measurement and from bulk-magnetization measurements with SQUID magnetometer. Currently, I am working on fabricating Nb-based micro-SQUID.
