The Halbach array is a new type of iron-free yoke multipole magnets made of rare earth materials proposed by physicist K.
In response to this problem, Yang Xiaodong's desktop magnetic resonance spectroscopy group at Suzhou Institute of Medical Technology proposed a passive shimming method based on the construction of a shimming array.
The passive shimming magnetic sheet array proposed in this work realizes the efficient compensation of the magnetic field of the Halbach magnet, and provides a strong support for China's independent research and development of high-resolution permanent magnet magnetic resonance spectrometers .
Related research results were published in the Journal of magnetic resonance under the title "A passive shimming method for Halbach magnet based on magnetic sheet arrays" .
