超导岩样磁力仪是以超导量子干涉器（SQUID）为磁传感器用来测量岩样剩磁的仪器,是研究岩石磁学和古地磁学的重要手段。它比常规的古地磁仪器——无定向磁力仪、旋转磁力仪具有灵敏度高、响应时间短、动态范围大、又可三分量同时测量等优点,满足了弱磁岩样测量的要求。本文叙述了超导测磁的理论基础,仪器的组成,原理,研制情况及实测结果。
A superconducting rock sample magnetometer （SRM）,used for measuring the remanent magnetization of rock sample,is constructed using a SQUID magnetic sensor. This is an important equipment in research for rock magnetism and paleomagnetism. Compared with other routine instruments i.e. the astatic magnetometer and spinning magnetometer,SRM,this instrument has higher sensitivity,wider dynamic range and faster response time. Besides,it can measure up to three orthogonal components of magnetization of the sample simultaneously without rotating or vibrating the sample.This paper presents the theoretical basis of superconducting rock sample magnetometer using SQUID and the structure of the instrument as well as measurement results.
