摘要：
The magnetic impurity effect on the Josephson current through mesoscopic tunnel junctions is investigated by numerically solving the Bogoliubov-de Gennes equations self-consistently. It is found that the presence of magnetic impurities in the middle layers significantly affects the current flowing across the junctions with d-wave superconductors. A 0 or pi state for the current-phase relation with a period of 2 pi can be realized when the thickness of middle magnetic impurity layers is varied. Moreover, the 0-pi or pi-0 transitions are demonstrated with increasing the temperature for Josephson junctions with specific interlayer thicknesses. (C) 2012 Elsevier B.V. All rights reserved.
