摘要: Publisher Summary This chapter focuses on spin-polarized tunneling in superconductors and ferromagnetic materials. The superconducting conductance technique is used for measuring the spin polarization of conduction electrons a material very different from 3d metals. Using spin-split film remains most unambiguous method tunnel current metal because long coherence length complete understanding theory experimental spectroscopy. In tunneling, derived imbalance density states spin-up spin-down at Fermi energy. Spin-polarized between ferromagnets show that metals are polarized with degrees characteristic each metal. electrodes extremely sensitive to surface interface properties short state.
