摘要註:	在本研究中我們利用超高真空電子束蒸鍍系統成長Al2O3(1-100) / V(200?) / NiFe(116 ?) 薄膜系統及利用濺鍍系統於陽極氧化鋁基板(AAO)上成長NiFe( x ? )，並探討其晶體結構與磁性質及磁翻轉機制之關係；於研究過程中，我們使用掃描式電子顯微鏡來觀察鎳鐵膜成長的結構形狀，以及利用磁光柯爾效應和震動樣品磁性量測儀來量測其磁滯曲線的變化，利用X-ray 繞射分析儀來做樣品結構的分析，並以磁力顯微鏡來觀察其在不同磁場下的磁區變化情形，再以電子順磁共振儀量測其磁滯及鐵磁共振行為。我們發現在Al2O3(1-100) / V(200?) / NiFe(116 ?) 薄膜系統時，利用釩來當種子層並改變最上層鎳鐵的成長溫度會影響其晶體排列方式，而磁滯曲線的方正度以及磁性質亦會受到晶體排列方向與外加磁場的方向不同而改變。另外在AAO / NiFe(x ?)系統方面，陽極氧化鋁基板的孔徑大小會影響鎳鐵膜的成長機制，一開始會在其孔洞周圍形成柱狀的奈米結構，隨著濺鍍時間增加進而形成network及連續膜，連帶的影響其磁性質的變化。 In this study, the V(200?) / NiFe(116 ?) trilayers are fabricated on Al2O3(1-100) substrates by the ultra-high e-beam evaporator and the different thickness of NiFe(x ?) are fabricated on the nanoporous anodic aluminum oxide (AAO) templates by sputtering. The crystal structures of NiFe are investigated by the scanning electron microscope and the X-ray diffraction. The hysteresis loops of NiFe are obtained by the Longitudinal mangeto-optical Kerr effect and the vibrating-sample magnetometer. The magnetic domain of NiFe in the different applied field are obtained by the magnetic force microscope. The ferromagnetic resonance behaviors are measured by the electron spin resonance. For the first time, the crystal structures of Al2O3(1-100) / V(200?) / NiFe(116 ?) have been influenced while V is been the seeding layer and permalloy layer is grown at different temperature. The squareness of the hysteresis loops have been changed in the different applied field. For the systems of AAO / NiFe(x ?), the microstructures of NiFe grown on AAO templates with different pore diameter strongly influence its magnetic properties. The NiFe nanorods are formed on the rim of the pores while the thickness of NiFe is thin. The network and continuous films were commonly formed for thick films for the longer deposition time.
