Radiation power and linewidth of a semifluxon-based Josephson oscillator
M. Paramonov, M. Yu. Fominsky, V. P. Koshelets +4
We demonstrate a high-frequency generator operating at ~200GHz based on flipping a semifluxon in a Josephson junction of moderate normalized length. The semifluxon spontaneously ap…
Electron sampling depth and saturation effects in perovskite films investigated by soft x-ray absorption spectroscopy
A. Ruosi, C. Raisch, A. Verna +5
Knowledge of the electron sampling depth and related saturation effects is important for quantitative analysis of X-ray absorption spectroscopy data, yet for oxides with the perovs…
Mn/Mn state of LaCeMnO by oxygen reduction and photodoping
Andreas Thiessen, Elke Beyreuther, Stefan Grafström +5
Films of cerium-doped LaMnO, which has been intensively discussed as an electron-doped counterpart to hole-doped mixed-valence lanthanum manganites during the past decade, were…
The effect of normal metal layers in ferromagnetic Josephson junctions
D. M. Heim, N. G. Pugach, M. Yu. Kupriyanov +6
Using the Usadel equation approach, we provide a compact formalism to calculate the critical current density of 21 different types of ferromagnetic (F) Josephson junctions containi…
Trapping of ultra cold atoms in a 3He/4He dilution refrigerator
F. Jessen, M. Knufinke, S. C. Bell +13
We describe the preparation of ultra cold atomic clouds in a dilution refrigerator. The closed cycle 3He/4He cryostat was custom made to provide optical access for laser cooling, o…
Dendritic flux avalanches in Niobium single crystal near critical temperature
M. Grünzweig, P. Mikheenko, C. Grünzweig +4
We report on the observation of dendritic flux avalanches in a large Niobium single crystal. In contrast to avalanches observed in thin films, they appear only in a very narrow tem…
