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…
