本實驗結合電子束蒸鍍與爐管製成，發現新的方式合成L10FePt/Carbon nanotube core/shell nanoparticle. 有別於以往製作鐵白金奈米粒子需要昂貴的鐵及白金前驅物，本次實驗使用價格經濟的鐵烯作為前驅物，同時將鐵烯作為鐵源和碳源，配合事先鍍好白金的基板，在爐管中反應後即可得到L10FePt/Carbon nanotube core/shell nanoparticle。此方法別於以往先長好鐵白金再將鐵白金當作催化劑生長碳管，也別與長好鐵白金奈米粒子後再和碳管混合；此方法可以一步直接得到L10FePt奈米粒子包覆在奈米碳管中。
分析奈米碳管中的鐵白金結構可以發現奈米碳管會壓縮其中的鐵白金，使其擁有較低的c/a ratio。同時元素比例分析結果配合高解析度穿透式電子顯微鏡影像分析顯示就算鐵與白金的元素比例離開了L10FePt相的邊界，外層的奈米碳管仍然會把其中的鐵白金結構維持在L10相的face center tetragonal結構而不是變成L12相的face center cubic結構。由此可看出碳管層包覆在外層可以幫助L10FePt序化。第二部分則是探討電子束照射對碳管層包覆的鐵白金奈米粒子的影響。實驗發現有碳管層包覆在外時，電子束照射會導致內核的鐵白金奈米粒子相變化，從L10FePt變成L12FePt3，也可以由L12Fe3Pt相轉變L10FePt。若外層沒有碳管層包覆，則是轉變成A1無序相。
本次實驗貢獻主要是發現新的方式合成L10FePt/Carbon nanotube core/shell nanoparticles 以及發現新的碳管層幫助鐵白金序化機制。

L10FePt, face center tetragonal structure with c/a ratio 0.964 and stoichiometry Fe100-xPtx (x=40-60), known as a ferromagnetic alloy with large uniaxial magneto-crystalline anisotropy and high coercivity, is successfully encapsulated in multi-walled carbon nanotubes (MWCNT). This synthetic method is a combined technique employing catalytic pyrolysis and electron beam deposition.
In this study, MWCNT can intensify the formation of L10 phase with smaller c/a ratio even the Fe/Pt ratio deviated from regular L10 FePt phase. Beside, locations of precursor will affect the reaction rate, causing different products eventually. Samples collected from varied locations of furnace show various crystallographic phases and magnetic coercivities as evident by XRD, SQUID and TEM.
