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…

The Ruthenocuprates - Natural Superconductor-Ferromagnet Multilayers
T. Nachtrab, C. Bernhard, C. T. Lin +2
The recently discovered ruthenocuprates have attracted great interest because of the microscopic coexistence of superconducting and ferromagnetic order. Typically, these materials…

Intrinsic Josephson Effects in the Magnetic Superconductor RuSr2GdCu2O8
T. Nachtrab, D. Koelle, R. Kleiner +2
We have measured interlayer current transport in small sized RuSr2GdCu2O8 single crystals. We find a clear intrinsic Josephson effect showing that the material acts as a natural su…
