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 spin?dependent forces detection and dark matter searches. The article summarizes the experimental results regarding spin?velocity dependent interactions, spin?gravity 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 spin?dependent forces, and to establish more rigorous limits of the coupling between axionlike dark matter and standard model fermions within a broader mass range.
