Inverse proximity effect in superconductors near ferromagnetic material
– We study the electronic density of states in a mesoscopic superconductor near a transparent interface with a ferromagnetic metal. In our tunnel spectroscopy experiment, a substantial density of states is observed at sub-gap energies close to a ferromagnet. We compare our data with detailed calculations based on the Usadel equation, where the effect of the ferromagnet is treated as an effectiv...

متن کاملDynamic ferromagnetic proximity effect in photoexcited semiconductors.
The spin dynamics of photoexcited carriers in semiconductors in contact with a ferromagnet is treated theoretically and compared with time-dependent Faraday rotation experiments. The long-time response of the system is found to be governed by the first tens of picoseconds in which the excited plasma interacts strongly with the intrinsic interface between the semiconductor and the ferromagnet in...
متن کاملGiant proximity effect in cuprate superconductors.
Using an advanced molecular beam epitaxy system, we have reproducibly synthesized atomically smooth films of high-temperature superconductors and uniform trilayer junctions with virtually perfect interfaces. We found that supercurrent runs through very thick barriers. We can rule out pinholes and microshorts; this "giant proximity effect" (GPE) is intrinsic. It defies the conventional explanati...
متن کاملEffect of ferromagnetic proximity on critical behavior
We have investigated the magnetic phase transition in amorphous Fe93Zr7(x Å)/Co95Zr5(1 Å) multilayers, where x = 25, 50, and 75. The extremely thin CoZr layer induces magnetic order at temperatures well above the inherent ordering temperature of Fe93Zr7. The changes in the critical exponent β, associated with the temperature dependence of themagnetization, imply a crossover from twoto three-dim...
