Microscopic Origin of the Enhanced Flux Pinning in Superconductors

Summary

This project aims to understand the microscopic origin of the critical current enhancement by nano chemical doping. The achievements of this project will deepen our understanding flux pinning mechanism, and will help to discovery practical MgB2-based superconductors for practical applications.

Synopsis

MgB2 is one of the most versatile superconducting materials ever discovered. The critical current density, a major bottleneck for many applications, has been significantly improved by introducing additional flux pinning through nano chemical doping. However, the microscopic origin and mechanism of the enhanced flux pinning has yet been fully understood. This project aims to understand the microscopic origin of the critical current enhancement by nano chemical doping. The achievements of this project will deepen our understanding flux pinning mechanism, and will help to discovery practical MgB2-based superconductors for practical applications.
