本實驗為了觀察鐵磁層與反鐵磁層之間磁矩的關係，我們希望能發展出一套標準程序來分析。我們使用X光吸收光譜 (X-ray Absorption Spectroscopy, XAS) 來確認樣品的成分，及樣品表層是否有反鐵磁層的存在，再利用影像式光電子顯微術 (photoemission electron microscopy, PEEM) 得到不同光源偏振性的磁區影像，將這些磁區影像使用影像處理軟體Image J把位置對應灰階程度數據化，透過分析XMLD-PEEM與XMCD-PEEM的圖譜，並搭配磁光柯爾效應 (Magnetic-Optic Kerr Effect, MOKE) 瞭解反鐵磁層跟鐵磁層自旋的空間相依性。由此，可以得知兩者是平行、垂直、或是歪斜的關係。提供spin-spin coupling的標準模式，不受肉眼判讀、PEEM解析度等等的干擾。此方法，不僅可以應用在分析磁性耦合，還可以用來分析任何兩張圖形的空間相依性。

We successfully develop a standard operating procedure to analysis the spatial correlation of the spins resolved from XMCD-PEEM and XMLD-PEEM images. The spins are aligned even the magnetic domains from the PEEM images that can be identified by naked eyes. To understand the relation between the ferromagnetic and antiferromagnetic. The sample composition was confirmed by X-ray Absorption Spectroscopy (XAS), and make sure dose the film have AM on surface layer or not. From the MOKE we can focus on the in-plane or out-plane magnetic field. Then, use the PEEM images and Image J to analysis sample, we can find that the relation between FM and AM.
