本研究在水溶液環境中利用電化學的方式成長Co薄膜在Cu(100)及graphene
/Cu上並進行磁性量測，再加入紫精酸的異質介面，研究Co薄膜在不同的介面對磁特性的影響，其中使用循環伏安法量測其成分組成，並使用磁光柯爾效應進行磁性量測。發現5至20 nm的Co薄膜在Cu(100)及graphene/Cu表面上成長，隨著厚度上升皆表現出縱向方向為磁化易軸，接著進一步分析縱向的磁滯曲線可以得到其飽和磁化量、殘磁、方正度以及矯頑力。Co/Cu(100)於不同電位測量時，其飽和磁化量、殘磁、矯頑力並無明顯的變化，而Co/graphene/Cu上則在特定的厚度會產生雙磁滯曲線疊加的現象，並且隨著電位可以控制其磁特性，比較石墨烯插層對Co/Cu薄膜的矯頑力影響，發現在任何電位下Co/Cu(100)薄膜的矯頑力皆大於Co/graphene
/Cu薄膜。而後在Co/Cu(100)上覆蓋紫精酸會使得較薄的Co膜其飽和磁化量與殘磁下降且矯頑力上升，但是至12 nm以上時便不受影響，然而Co/grap
hene/Cu於不同電位測量時，覆蓋紫精酸並無明顯變化。此研究發現在紫精酸及石墨烯之異質介面對Co薄膜受電位控制時的磁特性有微小的變化，對於開發電控制磁性元件附有應用潛力。
