本實驗乃是利用MBE系統成長高品質的[Co/Pt]多層膜，並選擇不同的種子層(Mo、Pt)與三種基板Al2O3 (0001、1-102、11-20)來成長出不同磊晶結構的[Co/Pt]多層膜，並觀察其在不同退火溫度下其磁性及結構的變化，藉由RHEED、x-ray繞射來探討其磊晶結構，PMOKE、VSM來量測其磁性，AFM、矯頑場分佈分析儀來觀察其原子表面型態及Hc分佈，觀察[Co/Pt]多層膜的結構與垂直異向性及磁光特性的關係。

Different crystal structure of high-quality epitaxial [Co/Pt] multilayers have been grown using different seeding layers(Mo or Pt) and substrates Al2O3(0001、1-102、11-20) by Molecular Bean Epitaxy (MBE) system . It is also be annealing in different temperature in this experiment to observe what is the relation between the annealing temperature and the structure and perpendicular magnetic anisotropic of [Co/Pt] multilayers.

The epitaxial structures of [Co/Pt] multilayers have been studied by Reflective High-Energy Electron (RHEED) and x-ray diffraction measurement. Perpendicular Magnetic-Optical Kerr Effect(PMOKE) and Vibrating Sample Magnetometry (VSM) measurement have been used to investigate the magnetic properties of [Co/Pt] multilayers .We also observed the atomic surface by using Atomic Force Microscope(AFM).
