Measurement of the spatial extent of inverse proximity in a Py/Nb/Py superconducting trilayer using low-energy muon-spin rotation

Physical Review B (2014)

M. G. Flokstra S. J. Ray S. J. S. Lister J. Aarts H. Luetkens

Muon-spin rotation has been used to observe directly the spatial variation of the magnetic flux density near the ferromagnetic-superconducting interface in a permalloy-niobium trilayer. Above the superconducting transition temperature ${T}_{c}$ the profile of the induced magnetic flux density within the niobium layer has been determined. Below ${T}_{c}$ there is a significant reduction of the induced flux density, predominantly near the ferromagnetic-superconducting interfaces. We are uniquely able to determine the magnitude and spatial variation of this reduction in induced magnetization due to the presence of the Cooper pairs, yielding the magnitude and length scale associated with this phenomenon. Both are inconsistent with a simple Meissner screening and indicate the existence of another mechanism, the influence of which is localized within the vicinity of the ferromagnetic interface.

Tunneling spectroscopy on the correlation effects in FeSi

Physical review. B, Condensed matter (1998)

M. Fäth J. Aarts A.A. Menovsky G. J. Nieuwenhuys J. A. Mydosh

We have performed electron tunneling spectroscopy on FeSi single crystals in the temperature range 4--300 K by using a scanning tunneling microscope. The differential conductance $(dI/dV),$ when corrected for Schottky barrier effects, exhibits two strongly temperature-dependent peaks on either side of the Fermi level that emerge below $\ensuremath{\approx}200$ K and that are separated by a (pseudo)gap of $\ensuremath{\approx}50$ meV. Our observations can be ascribed to the formation of quasiparticle density of states caused by d-electron correlation. The tunneling spectra are in good agreement with photoemission spectroscopy as both techniques probe the correlated d-electron density of states (DOS). Our results are also consistent with optical reflectivity data and Raman spectroscopy, which, in contrast, are sensitive to the conduction $(c)$ electron DOS.
