Description

An unconventional iron superconductor, SmO[subscript 0.7]F[subscript 0.3]FeAs, has been utilized to determine the spin polarization and temperature dependence of a highly spin-polarized material, La[subscript 0.67]Sr[subscript 0.33]MnO[subscript 3], with Andreev reflection

An unconventional iron superconductor, SmO[subscript 0.7]F[subscript 0.3]FeAs, has been utilized to determine the spin polarization and temperature dependence of a highly spin-polarized material, La[subscript 0.67]Sr[subscript 0.33]MnO[subscript 3], with Andreev reflection spectroscopy. The polarization value obtained is the same as that determined using a conventional superconductor Pb but the temperature dependence of the spin polarization can be measured up to 52 K, a temperature range, which is several times wider than that using a typical conventional superconductor.
