  • Josephson junction and Josephson device
    Patent number: 8200304
    Abstract: A novel Josephson junction and a novel Josephson junction device are provided which eliminates the need to form an insulating barrier layer. The Josephson junction (1) comprises a superconductor layer (2) and a ferromagnetic layer (3) formed on a middle part (2C) of the superconductor layer (2). The ferromagnetic layer (3) may consist of an electrically conductive or insulating ferromagnetic layer, and may be an electrically conductive ferromagnetic layer formed via an insulating layer. With the superconductor layer (2) formed of a high temperature superconductor, a Josephson junction (1) is provided having large IcRN product. The Josephson junction (1) can be used as a junction for a variety of Josephson devices.
