The magnetic flux periodicity in SNS square ring.

POSTER

Abstract

In this work, we study the magnetic flux periodicity of d-wave superconductor-normal-superconductor square ring. The Hamiltonian of the SNS square ring is solved by using self-consistent Bogoliubov-de Gennes equations. The total current as a function of flux exhibits the hc/e period. As we increase the length of the normal metal, the hc/e period becomes hc/2e period. Furthermore, we also investigate the behavior of the supercurrent in SNS and SIS junctions and the phase variation of the Josephson current.
