Abstract: Ultrasensitive atomic magnetometer and co-magnetometer have provided powerful tools for study the material world. These devises are widely used in imaging of biomagnetic signals and frontier physics research, such as magnetocardiography, magne-toencephalography, searching for dark matter and fifth force, measurement of permanent electric dipole moment and violation of fundamental symmetry. Magnetic anomaly detection and high-precision inertial navigation systems also urgently need these devices. Improving the sensitivity records and building ultra-low magnetic field environment are pivotal for further researches of fundamental physics, biomagnetic imaging and major national needs. Firstly, the schematic introductions of Ultrasensitive atomic magnetometer and co-magnetometer as well as fundamental studies are present, including the working principle, exper-iment setup, and theoretical modal. Secondly, the schematic introductions of atomic magnetometers and magnetic shield room are present, specifying the ways to improve the performance. Meanwhile, the research on physical properties in the strong magnetic field environment has achieved fruitful results, but the basic scientific research in the extremely weak magnetic field environment is very scarce. Based on the ultrasensitive atomic magnetometer, co-magnetometer and magnetic shield room, Zero-Magnetism Science is proposed in this paper, which utilizes ultra-low magnetic field environment, ultrasensitive magne-tometer, and precise magnetic field manipulation to study basic scientific researches, including zero-magnetism medicine, zero-magnetism biology, zero-magnetism chemistry and zero-magnetism materials science, promising for constructing a sys-tem theory of "Zero-Magnetism Science".
