2015年2月2日 · Abstract: The magnetic field dependence of the Eck step voltage in long Josephson tunnel junctions (LJTJs) can be exploited for ultralow-noise magnetic sensing.
Ultra-low-noise magnetic sensing with long Josephson
2013年10月17日 · We study how the magnetic field dependence of the Eck step voltage in long Josephson tunnel junctions (LJTJs) can allow for ultra-low-noise magnetic sensing. The field to be measured is applied perpendicular to a continuous superconducting pickup loop.
Current-voltage characteristic of a LJTJ in presence of different ...
The magnetic flux to be measured is captured by a non-interrupted superconducting pickup loop in which a narrow constriction, forming the LJTJ wiring layer, produces a local high density ...
Long Josephson Junction in Ultralow-Noise Magnetometer Configuration
2015年1月1日 · The magnetic field dependence of the Eck step voltage in long Josephson tunnel junctions (LJTJs) can be exploited for ultra-low-noise magnetic sensing.
Electrode Long Josephson Tunnel Junction (DOCELJTJ), consists of a LJTJ for which at least one electrode is shaped as a loop. This device is sketched in Fig.1 in which the junction bottom electrode is in black, while the top electrode - in the shape of a rectangular thin- lm
Interaction of Josephson vortices with a chain of trapped …
1994年2月2日 · LINTRODUCTION It is well established theoretically that Abrikosov vortices (A-vortices) trapped in a region of a long Josephson tunnel junction (LJTJ) (one of a junction dimension is larger than the Josephson penetration depth (k )) can be described as local magnetic impurities which are able to act as pinning centers for the Josephson vortices ...
planar LJTJ for which at least one of the superconducting electrodes is multiply-connected, i.e., not every closed path can be transformed into a point. In the simplest case, one of the superconducting thin- lm stripes forming the LJTJ is shaped as a doubly-connected loop.
Superconducting flux-flow type ultra-low-noise magnetic sensors
2013年4月21日 · A superconducting magnetometers based on the magnetic field dependence of the Eck step voltage in long Josephson tunnel junctions (LJTJs) is demonstrated. The field to be measured is applied perpendicular to a continuous superconducting pickup loop.
Noise performance of superconductive magnetometers based on …
2014年8月13日 · In a recent proof of principle experiment a constant field responsivity, in range, has been reported by simply shaping the wiring layer of an all-niobium LJTJ in a 1 cm 2 loop perpendicular to the applied magnetic field.
