Dr. Yinan Hu from Institute of Biophysics, Chinese Academy of Sciences visited APM

    On May 26, 2023, Dr. Yinan Hu was invited to give an academic report entitled "Miniaturized Atomic Magnetometer Technology and Its Application in Portable NMR Relaxometry" at the 1819 conference room of the Spectrum Building. The report was chaired by Associate Professor Li Wang.

    Dr. Hu studied at Central South University and received his master's degree from the Institute of High Energy Physics of the Chinese Academy of Sciences, and served as a magnetoencephalography engineer at the Institute of Biophysics, Chinese Academy of Sciences. In 2021, he received his PhD degree in atomic physics from the Helmholtz Institute in Germany and the University of Mainz, and returned to China in the same year. Dr. Hu's main research interests are non-contact detection technology based on miniaturized atomic magnetometers. He has participated in the construction of the first superconducting quantum interferometer (SQUID) magnetoencephalography system for scientific research in China, developed a high-sensitivity atomic magnetometer (OPM) and miniaturized it for practical research. Additionally, he carried out the exploration of OPM-based nano-magnetic particle detection technology and the development of high-precision magnetic field stabilization systems applied to future biomagnetic measurement, zero-magnetic science, national defense security, and deep space exploration.

    In the report, Dr. Hu explained the working principle, miniaturization scheme, non-contact detection application, and future development prospects of zero-field single-beam quantum magnetometers. He introduced the work in applications such as brain magnetometers, zero to ultralow field nuclear magnetic resonance induced by para-hydrogen, and magnetic field detection of lithium-ion batteries. Based on recent research results and related experimental content, Dr. Hu introduced in detail various miniaturization schemes for magnetometers and emphasized the importance of miniaturized atomic magnetometers for current and future applications.

    After the presentation, Dr. Hu visited the atomic magnetometer laboratory and the 3T and 9.4T MRI laboratories. During the visit, he had in-depth discussions and exchanges with the faculty and students of the research group.
