Andreev bound states at a cuprate grain boundary junction: A lower bound for the upper critical field

M. Wagenknecht, D. Koelle, R. Kleiner +6

We investigate in-plane quasiparticle tunneling across thin film grain boundary junctions (GBJs) of the electron-doped cuprate La $_{2 - x}$ Ce $_{x}$ CuO $_{4}$ in magnetic fields up to $B…

Laser microscopy of tunneling magnetoresistance in manganite grain-boundary junctions

M. Wagenknecht, H. Eitel, T. Nachtrab +4

Using low-temperature scanning laser microscopy we directly image electric transport in a magnetoresistive element, a manganite thin film intersected by a grain boundary (GB). Imag…
