  • Multilayer thin film hall effect device
    Patent number: 5517170
    Abstract: A Hall effect device and a method of obtaining a magnetic field map of a magnetic body with the Hall effect device. The device comprises: (1) a substrate, (2) a first layer having a first Hall coefficient deposited over the substrate and (3) a second layer having a second Hall coefficient deposited over the first layer, the first and second layers cooperating to create, in the Hall effect device, a third Hall coefficient different from the first and second Hall coefficients. Creation of the third Hall coefficient by cooperation of the first and second layers allows use of materials for the first and second layers that were previously unavailable for Hall effect devices due to their relatively weak Hall coefficient.
    Type: Grant

  • Germanium coated microbridge and method
    Patent number: 4055847
    Abstract: A superconducting microbridge is provided for use in superconducting quantum interference devices wherein a pair of spaced layers of superconductive material are connected by a weak link bridge to establish an electrical junction. The superconductive layers and bridge are coated with a semiconductor material shunting the bridge at room temperatures to prevent the destruction of the device by minute electrical currents while the coating acts as a dielectric permitting normal electrical behavior of the microbridge at cryogenic temperatures.
