〔産業上の利用分野〕
本発明は超電導材を電子素子間の配線材として用いた電
子装置、特に大電流密度の直流あるいは低周波電流を使
用する電子装置に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an electronic device using a superconducting material as a wiring material between electronic elements, and particularly to an electronic device using a direct current or low frequency current of high current density.
従来の電子装置、例えば集積回路に用いられる配線は、
例えばｒＭＯ８ＬｓＩ技術」日経マグロウヒル社（１９
８４年）第１２１頁に記載されているようにＡＱなとの
常伝導金属が用いられるのが通常であった。The wiring used in traditional electronic devices, such as integrated circuits, is
For example, "rMO8LsI technology" Nikkei McGraw-Hill (19
As described on page 121 (1984), a normal conducting metal such as AQ was usually used.
□つＯｒ
上記従来技術においては、低周波信号線或いは直流給電
線での隣接配線からの影響は考慮する必要はなかった。□Or In the above-mentioned conventional technology, there is no need to consider the influence from adjacent wiring on the low frequency signal line or the DC power supply line.
しかし、配線材に超電導材を用いた場合、隣接する配線
からの磁界の影響により、とくに臨界に近い大電流密度
配線の場合は超電導状態が保ち難くなるという問題があ
る。However, when a superconducting material is used as a wiring material, there is a problem in that it becomes difficult to maintain a superconducting state, especially in the case of wiring with a high current density close to criticality, due to the influence of magnetic fields from adjacent wirings.
本発明の目的は、隣接する低周波、或いは直流配線から
の磁界の影響を低減し、大電流密度においても超電導状
態を保ちやすくすることにある。An object of the present invention is to reduce the influence of magnetic fields from adjacent low-frequency or DC wiring, and to facilitate maintaining a superconducting state even at high current density.
上記目的は、隣接した２木の配線中を流れる電流の向き
を互に反対にすることで達成できる。すなわち、２本の
配線中を流れる電流のベクスル成分のうち、互に平行な
成分の向きを反対にすることで達成できる。The above object can be achieved by reversing the directions of currents flowing through two adjacent wires. That is, this can be achieved by reversing the directions of the parallel components of the Vexal components of the current flowing through the two wires.
隣接する配線に流れる電流の向きが反対であれば電流に
より発生する磁界は互いに打ち消し合い、その結果磁界
の影響は少なくなり、超電導状態は破れ難くなる。If the directions of the currents flowing through adjacent wires are opposite, the magnetic fields generated by the currents cancel each other out, and as a result, the influence of the magnetic fields is reduced, making it difficult to break the superconducting state.
以下実施例により本発明を説明する。 The present invention will be explained below with reference to Examples.

反射にする。この場合、各超電導線に、臨界電流値に近
い大電流を流しても、超電導状態が破れることはなかっ
た。超電導線１は臨界電流値に近い大電流が流れている
ので、少しでも磁場が加われば超電導状態が破られる状
態にあるが、超電導線２によって生じる磁場は超電導線
１によって生じる磁場と相殺するので、超電導線１には
磁場は印加されず、超電導状態が破れることはない。(Example 1) - Fig. 1 shows an example of the present invention. Two superconducting wires 1 and 2 whose main components are barium, yttrium, and oxidized steel are arranged adjacent to each other in parallel, and the direction of the current (indicated by the arrow in the figure) is set to reflect. In this case, even when a large current close to the critical current value was passed through each superconducting wire, the superconducting state was not broken. Since a large current close to the critical current value is flowing through the superconducting wire 1, the superconducting state will be broken if even a small magnetic field is applied, but the magnetic field generated by the superconducting wire 2 cancels out the magnetic field generated by the superconducting wire 1. , no magnetic field is applied to the superconducting wire 1, and the superconducting state is not broken.
