本實驗透過電子束蒸鍍儀系統成長出15 nm/15 nm的Permalloy/Platinum雙層磁性材料透過銅箔及金製成的共平面波導(Coplanar waveguide，CPW)輸入微波訊號使樣品產生自旋轉矩鐵磁共振(Spin- torque Ferromagnetic resonance，ST-FMR)時在該結構的兩端量到一個電壓差(Vmix)並推算出其磁化飽和強度(Saturation magnetization，Ms)，其在自旋電子學之應用中扮演相當重要的角色，它的實用性和廣泛使用主要是因為它是一種共振現象，其中較有效率的方法則是利用本身具有強自旋軌道耦合(Spin-orbit-coupling，SOC)的材料(如重原子金屬)中所發現的自旋霍爾效應(Spin Hall effect，SHE)。其能產生方向和外加電流垂直的自旋電流。本實驗有助於了解所產生的信號Vmix，由勞倫茲式(Lorentzians)及反勞倫茲式(Anti-Lorentzian)的組合，並透過測量不同頻率與磁場變化的共振磁場相關性比較其他不同製程找出品質穩定且較優良的方法，並分析出我們的自旋轉換效率為0.2044與其他期刊比較有較高的轉換效率，以及對角度變化的依賴性及各項力矩貢獻。
