Critical Current Density Improvement in Type II Superconductors by Modifying the Type, Size and the Patterns of Pinning Centers, M.Sc. Thesis Sharif University of Technology ; Vesaghi, Mohammad Ali (Supervisor) ; Fardmanesh, Mehdi (Supervisor)
Abstract
Motion of magnetic flux, as a result of exerting electrical current, causes dissipation and voltage difference in the type II superconducting slab. So fixing these vortices by pinning centers will increase the critical current . Enhancing the critical current by different kinds of pinning centers is interesting for a lot of theoretical and experimental research groups. At first in this project dynamics of vortices in a triangular lattice is investigated by changing the pinning force. For the case of fp=2f0 we have seen two phase transition in velocity-force plot. And also a practical pinning array of parallel lines is presented. The effect of pinning force, pinning potential width and the...
