摘　　要：简述了异常相互作用力及类轴子暗物质的理论模型,回顾了近年来国内外研究人员使用原子磁力仪和共磁力仪等进行自旋相关的非磁性力探测和暗物质搜寻的技术方案,归纳了迄今为止对自旋和速度相关相互作用、自旋引力相互作用、类轴子暗物质场梯度与核子的耦合强度的探测结果。在此基础上,本文对该领域未来的发展方向进行了展望,通过分析和抑制系统误差、寻找新的探测方案等方法,有望为自旋相关相互作用的耦合参数空间提供更严格的约束,在更广泛的质量范围内对类轴子暗物质与标准模型费米子的耦合给出更严格的界定。This article provides a brief overview of the theoretical models of anomalous interactions and axionlike dark matter.It reviews the technical approaches of domestic and foreign researchers in recent years,including atomic magnetometers and comagnetometers,for exotic spindependent forces detection and dark matter searches.The article summarizes the experimental results regarding spinvelocity dependent interactions,spingravity interactions,and the coupling strength between the gradient of axionlike dark matter field and nucleons.On this basis,it provides an outlook for the future development direction in this field.By analyzing and suppressing systematic errors,and exploring new experimental schemes,it is expected to provide more stringent constraints for the coupling parameter space of spindependent forces,and to establish more rigorous limits of the coupling between axionlike dark matter and standard model fermions within a broader mass range.
