摘　　要：超导现象是一种宏观量子现象.磁通量子化和约瑟夫森效应是两个最能体现这种宏观量子特性的物理现象.超导量子干涉器件(superconducting quantum interference device,SQUID)是利用这两个特性而形成的超导器件.SQUID器件在磁信号灵敏探测方面具有广泛的应用.本文简要介绍低温超导和高温超导SQUID器件的相关背景和发展现状以及应用领域.Superconductivity is a macroscopic quantum phenomenon.Flux quantization and the Josephson effect are two physical phenomena which can best reflect the macroscopic quantum properties.Superconducting quantum interference device(SQUID)is one type of superconducting devices which uses these two characteristics.SQUID devices are widely used in the sensitive detection of magnetic signals.This paper briefly introduces the background and recent developments of low temperature superconductor and high temperature superconductor SQUID devices.
