摘要： The invention relates to an electronic component with a Josephson junction and to a production method. The component comprises a substrate (1.1) with at least one step edge in the substrate surface and a layer which is arranged on said substrate and which is made of a high-temperature superconductive material (1.4). The layer has a grain boundary (1.5) at the step edge, said grain boundary forming the one or two weak link(s) of the Josephson junction. According to the invention, the a- and/or b-crystal axes on the plane of the high-temperature superconductive layer are made to run perpendicularly to the grain boundary with a maximum tolerance of 10° on both sides of the step edge by texturing the substrate and/or at least one buffer layer arranged between the substrate and the high-temperature superconductive layer. This can be technically implemented by growing the HTSC layer in a graphoepitaxial manner for example. By orienting the same crystal axis perpendicularly to the step edge on each side of the step edge, a maximum supercurrent can flow across the grain boundary induced by the step edge and thus across the Josephson junction.

摘要： Die Erfindung betrifft ein Messinstrument für zeitveränderliche magnetische Flüsse oder Flussgradienten, elektrische Widerstandselemente sowie ein Messsystem mit einem erfindungsgemäßen Messinstrument oder elektrischen Widerstandselement. Kernstück des Messinstruments ist ein Flusstransformator aus einem Basismaterial, das einen Phasenübergang zum supraleitenden Zustand besitzt. Dieser Flusstransformator weist erfindungsgemäß auch dann, wenn sich das Basismaterial im supraleitenden Zustand befindet, mindestens einen Verbraucherbereich mit von Null verschiedenem elektrischen Widerstand zur Dissipation der elektrischen Energie in seiner Leiterschleife auf. Dabei sind die Leiterschleife und die Magnetfeldquelle erfindungsgemäß in einer Ebene angeordnet und im Regelfall fotolithografisch strukturiert. Als Kernkomponente in dem Messinstrument sind die erfindungsgemäßen Widerstandselemente mit Widerstandswerten ≦̸ 10&OHgr; verwendbar. Erfindungsgemäß werden Messungen in einem breiteren Frequenzbereich, mit geringerem Rauschen und mit größerer Empfindlichkeit ermöglicht, als dies mit gattungsgemäßen Messinstrumenten oder Messsystemen möglich war.

摘要： The invention concerns a layered arrangement comprising at least one layer based on a high-temperature superconductive material with at least one unit cell having a CuO2 plane, the layer being connected to a non-supeconductive layer. A modified interface layer is provided between the two layers. Alternatively, at least one of the contacting layers can be modified in the interface region. Modification can be brought about by doping with metallic ions or implantation.

摘要： Im Rahmen der Erfindung wurde ein Sputterkopf mit einer Aufnahme-Fläche für ein Sputtertarget (Target-Aufnahme) entwickelt. Der Sputterkopf weist eine oder mehrere Magnetfeldquellen zur Erzeugung eines magnetischen Streufelds auf. Erfindungsgemäß sind der magnetische Nordpol und der Südpol mindestens einer Magnetfeldquelle, zwischen denen sich das Streufeld ausbildet, 10 mm oder weniger, bevorzugt 5 mm oder weniger und ganz besonders bevorzugt etwa 1 mm, voneinander entfernt. Es wurde erkannt, dass gerade beim Sputtern unter hohem Sputtergas-Druck 0,5 mbar oder mehr durch ein solchermaßen lokal wirksames Magnetfeld der Ionisationsgrad des Sputterplasmas und damit auch die Abtragrate auf dem Sputtertarget lokal angepasst werden können. Dadurch wird die Dicke der erhaltenen Schichten über die Substratoberfläche homogener. Vorteilhaft weist der Sputterkopf zusätzlich einen Festkörperisolator auf, der den Grundkörper mit der Target-Aufnahme-Fläche sowie das Sputtertarget (alles auf Potential) umgibt und von der Abschirmung, die den Materialabtrag räumlich auf das Sputtertarget beschränkt (auf Masse), elektrisch isoliert.
