高長寬比橢圓有 3 種翻轉模式、buckling mode、mixed mode、vortex mode。橢圓會透過三種模式之一完成磁化翻轉但必須此模式在該尺寸擁有三者 使用Stoner–Wohlfarth model 說明橢圓薄膜皺褶態矯頑場角度相一性,但 Stoner–Wohlfarth model 的曲線無法有效擬合本研究數據,可能需要進一步了 解皺褶態的邊界條件,方能更近一步使用Stoner–Wohlfarth model 解釋。磁場 角度𝜃𝜃 ≠ 0°,會使得厚度 vs 矯頑場曲線的最高點的厚度會增加,這是磁荷距離 增加,有利於皺褶並抑制渦旋。此外,透過磁阻的模擬有助於判定磁場方向,

提供更直觀的方法檢驗磁場走向。
