At low temperatures, a midgap Andreev resonant state anomalously enhances not only the charge current but also the spin current. The coupling between the Cooper pairs and the electromagnetic fields leads to a Fraunhofer pattern in the direct current spin flow in magnetic fields and an alternative spin current under applied bias voltages.American Physical SocietyJournal Articleapplication/pdfhttp://hdl.handle.net/2115/17201https://eprints.lib.hokudai.ac.jp/dspace/bitstream/2115/17201/1/PRB74-22.pdf0163-18291095-3795Physical Review B74222205012006-12enginfo:doi/10.1103/PhysRevB.74.220501Copyright © 2006 American Physical Societypublisher
