Exploring the evolution of Earth’s magnetic field and analyzing the magnetic properties and geochronology of specific minerals are crucial aspects of our research. The magnetic domain structure of magnetic minerals is measured using the magnetic force microscopy (MFM), whereas magnetic parameters (such as magnetization and coercive field) are measured by employing the superconducting quantum interference device (SQUID). Additionally, dating studies are conducted using inductively-coupled plasma mass spectrometry (ICP-MS). By integrating relevant information, a comprehensive understanding of the variations in ancient and modern magnetic fields can be revealed.
 

磁力顯微鏡在古地磁之研究：

我們試圖探索地球磁場之演變，磁性礦物之磁特性量測和年代學的分析至關重要。利用磁力顯微鏡量測磁性礦物磁區結構，並使用超導量子干涉儀等儀器測量磁化量和矯頑磁場等磁學參數；再透過雷射剝蝕感耦合電漿質譜儀進行相關定年研究，結合相關資訊可進一步確定古今磁場之轉變。
