我们调查的磁场保存在一个含有铁化合物，如墨水颜料或血液染色的方向，使用超导量子干涉仪（SQUID）磁强计系统。通过应用矢量型SQUID梯度仪和机械调制来观察布或纸样品的磁化，矢量型SQUID梯度仪检测磁场的三个正交分量，机械调制将直流磁信号转换为SQUID可检测的时变信号。数值实验表明，当样品在探头下作直线运动时，矢量型SQUID磁强计可以识别样品的磁化方向。本文详细介绍了测量系统的仪器和原理验证实验，以确认系统的有效性。所获得的结果表明，含铁化合物的染色剂的磁化保留了它们产生的磁场的方向，正如我们假设的那样。
We investigate the orientation of the magnetic field preserved in a stain containing iron compounds, such as ink pigment or blood, using a superconducting quantum interference device (SQUID) magnetometer system. The magnetization of a cloth or paper sample is observed by applying a vector-type SQUID gradiometer, which detects three orthogonal components of the magnetic field, and mechanical modulation, which converts dc magnetic signals to time-varying signals detectable by SQUIDs. Numerical experiments indicate that the orientation of the magnetization could be identified by the vector-type SQUID magnetometer when the sample was moved linearly under the probe. This paper describes in detail the instrumentation of the measurement system and a proof-of-principle experiment to confirm the system's effectiveness. The obtained results suggest that the magnetization of iron-compound-containing stains preserved the orientation of the magnetic field in which they were produced, as we hypothesized.
