Triplet superconducting proximity effect in nonhomogeneous magnetic materials
We show that quantum spin fluctuations in inhomogeneous conducting ferromagnets drastically affect the Andreev reflection of electrons and holes at a ferromagnet- superconductor interface. As a result, a strong long-range proximity effect appears, associated with electron-hole spin triple...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Резюме: | We show that quantum spin fluctuations in inhomogeneous conducting ferromagnets
drastically affect the Andreev reflection of electrons and holes at a ferromagnet-
superconductor interface. As a result, a strong long-range proximity effect appears,
associated with electron-hole spin triplet correlations and persisting on a length scale
typical for nonmagnetic materials but anomalously large for ferromagnets. For applications,
an important consequence is that this long-range proximity effect permits to create
superconducting quantum intetference devices with the Josephson magnetic junction of an
anomalous large length. |
