Imaging of order parameter induced phase shifts in cuprate superconductors by low-temperature scanning electron microscopy
Christian Gürlich, Edward Goldobin, Rainer Straub +6
Low-temperature scanning electron microscopy (LTSEM) has been used to image the supercurrent distribution in ramp-type Josephson junctions between Nb and either the electron-doped…
Imaging of Thermal Domains in ultrathin NbN films for Hot Electron Bolometers
D. Doenitz, R. Kleiner, D. Koelle +2
We present low-temperature scanning electron microscopy (LTSEM) investigations of superconducting microbridges made from ultrathin NbN films as used for hot electron bolometers. LT…
1/f noise from vortex-antivortex annihilation
K. Langfeld, D. Doenitz, R. Kleiner +1
The magnetic flux noise induced by vortices in thin superconducting films is studied. Rigid vortices in thin films as well as pancake vortices in the pancake gas regime are address…
Observation of Andreev bound states in YBaCuO/Au/Nb ramp-type Josephson junctions
B. Chesca, D. Doenitz, T. Dahm +6
We report on Josephson and quasiparticle tunneling in YBa2Cu3O7-x(YBCO)/Au/Nb ramp junctions of several geometries. Macroscopically, tunneling occurs in the ab-plane of YBCO either…
Microscopic Analysis of Low-Frequency Flux Noise in YBaCuO Direct Current Superconducting Quantum Interference Devices
D. Doenitz, R. Straub, R. Kleiner +1
We use low-temperature scanning electron microscopy combined with SQUID detection of magnetic flux to image vortices and to investigate low-frequency flux noise in YBaCuO$_…
