摘要： During the manufacture of Josephson superconducting devices, it is necessary to provide on a substrate a base electrode, a counter electrode and a small tunnel barrier area therebetween. A novel method of making all three of these active elements in the same vacuum chamber without having to remove the substrate from the vacuum chamber is provided so that the tunnel barrier area is accurately made to a predetermined size and without the danger of contamination. The novel structure is made as a substantially planarized laminate in the vacuum chamber and the tunnel barrier area is defined in a supplemental step.

摘要： Consecutive bit bubble memory devices employ a dummy detector element separated from the detector element. This arrangement causes substantial background magnetoresistor noise. The dummy detector of the present invention is located in a novel dummy array which minimizes the magnetoresistor noise, enhances the signal-to-noise ratio and enables the detection of bubble domains without error.

摘要： A magneto-optic Kerr effect hysteresis loop measuring apparatus is provided which employs a small relatively low weight ring magnet having a small gap and a high magnetic field strength in the deep gap and in the adjacent external gap. The spot on the product which is to be non-destructively tested is placed in the external gap field next to the small gap in a region of saturating magentic field. A laser beam having a high polarization ratio is directed along an incident path to the spot on the surface of the product to be non-destructively tested and the reflected beam is processed in a Kerr effect detector to provide hysteresis loop data which is capable of providing information sufficient to determine the squareness of the hysteresis loop and the coercivity of the material being non-destructively tested.

摘要： A novel method of depositing the oxide barrier junction on a base electrode of a Josephson junction device is provided. An ionized oxygen plasma region is generated juxtaposed the surface of the base electrode to be oxidized. The pressure of the oxygen in the vacuum chamber is held at a predetermined high pressure where the zero voltage supercurrent is found to be independent of oxygen pressure variations and the flow of oxygen through the vacuum chamber is stabilized at the optimum minimum necessary for growth of the oxide barrier junction. The oxide barrier junctions so produced have consistent and predictable supercurrent densities.

摘要： A single Josephson junction device is arranged in a single branch which comprises an external source resistor connected in series with an output resistor and a Josephson junction device. An input node and an input resistor are in series and connected to the node between the output resistor and the Josephson junction device. Voltage signals applied to the input voltage node are amplified by connecting a high gain voltage output in parallel with the output resistor and providing sensing means for sensing the voltage output across the output resistor only when the Josephson junction device is switching from its low impedance state to its high impedance state.

摘要： Apparatus for measuring hysteretic properties of thin film recording disks is provided which comprises a magnetic field generator for magnetizing a spot on a piece of magnetic material to be tested. The magnetized spot is moved past a stationary Hall effect sensor which detects the magnetic flux being emitted from the magnetized spot. The process of magnetizing and detecting the flux emitted from the same spot is repeated at different magnetization levels to provide a set of automatic measurements that are recorded in a memory of a controller processor. An analysis of the recorded data permits the automatic computation of residual flux, remanent coercivity, switching field distribution as well as other hysteretic properties.
