基于铷原子系综的等温剩磁检测系统研究
Research on an isothermal remanent magnetization detection system based on the rubidium atomic ensemble
摘要
Abstract
Isothermal remanent magnetization(IRM)is an important research topic in the analysis of material magnetic characteristics.However,owing to its low sensitivity,large volume,and high maintenance cost,the classical IRM measurement system cannot satisfy the practical requirements.Therefore,it is necessary to develop the IRM measurement system to attain a high sensitivity and small size.The magnetic field measurement technology based on the rubidium atomic ensemble has the advantages of high sensitivity and small size;accordingly,in this study,an IRM measurement system based on rubidium atomic ensemble is proposed.Here we focus on the design process regarding the magnetization device and residual magnetism detection device.More importantly,the IRM measurement system can successfully detect the soil samples collected from the Cherry River in Minhang Campus of East China Normal University.Our research demonstrates that the proposed detection system is easy to operate and maintain.Moreover,it has significant application prospects in the fields of environmental magnetism,geological exploration,and biological magnetic field measurement.关键词
