    Controversial Issues of Hydrocarbon Field Formation and the Role of Geomagnetic Fields by Andrey A. Ponomarev, Marsel A. Kadyrov, Yuri V. Vaganov, Valeria A. Cheymetova, Vadim M. Aleksandrov, Aleksandr V. Morev

    Published 2022-01-01
    “…We also present the leading causes of discrete magnetic fields in the sedimentary cover: Earth’s geomagnetic reversals, generation of ferromagnetic minerals in oil deposits, electromechanical effects of rock friction near faults, and intermixing of reservoir waters with different mineralization (spontaneous ion polarization). …”

    Optimization of microstructure for HRE-free Nd-Fe-B magnets with improved properties by Yuxin Zhao, Rui Han, Meng Zheng, Xun Duan, Xiaoning Shi, Xianjun Hu, Hongsheng Chen, Dong Zhou, Shengzhi Dong, Wei Li

    Published 2025-03-01
    “…Furthermore, first-order reversal curve (FORC) analysis confirmed that the fine-crystalline magnets exhibit superior temperature stability, attributed to a reduced local demagnetization field and a more independent demagnetization process.…”

    Synergistic regulation and optimization of microstructure, coercivity, and thermal stability in sintered NdFeB magnets through grain boundary diffusion of Dy and Al elements by Rui Chang, Guangzhu Bai, Yaping Li, Zhi Yan, Xiufang Qin, Jingdong Guo, Fang Wang, Xiaohong Xu

    Published 2025-01-01
    “…The grain boundary diffusion process (GBDP) is a well-established method for producing high-performance NdFeB magnets. However, the limited diffusion ability of heavy rare earth (HRE) elements, which are only attached to the surface of the magnet, has been a major concern in the industry. …”
