Research Area

1. Development of High-Performance, Low Magnetic Noise Soft Magnetic Shielding: Spearheaded the development of magnetic shields using soft magnetic materials such as permalloy, ferrite, and amorphous/nanocrystalline alloys. Proposed a comprehensive magnetic noise calculation model for hybrid shielding systems incorporating multiple soft magnetic materials, and established a corresponding design methodology for low-noise systems. This work clarified the relationship between the overall magnetic noise and the performance parameters of the magnetic shields, thereby guiding the design of high-performance, low-noise soft magnetic shielding systems. These systems provide a stable, low-noise, and low-remanence environment essential for SERF magnetic field measurement devices.

2. Development of Superconducting Magnetic Shielding: Pioneered the development of a novel ultra-low-noise magnetic shielding system that integrates superconducting coils with soft magnetic materials. This approach effectively reduces magnetic noise and breaks through the performance bottleneck limited by traditional soft magnetic shields, providing key technical support for enhancing the sensitivity of SERF magnetometers. Furthermore, introduced a design methodology for superconducting coil magnetic shielding that incorporates a correction factor, significantly improving the design accuracy of the superconducting coils and enhancing their overall shielding performance.
