摘要
有機的錳酞花青分子可以成功地被鍍在銅(111)以及鈷/銅(111)的平台上，且由掃描穿隧電子顯微鏡量測的表面形貌所證實。除此之外，在錳酞花青/鈷/銅(111)系統中，所有的錳酞花青分子均可被鈷的奈米島狀結構所捕捉而非銅的基板。再者，利用低溫自旋偏極化掃描穿隧電子顯微鏡及光譜，不僅是島狀的鈷，錳酞花青分子的自旋偏極化能態也可在4.5Ｋ被解析。而且錳酞花青分子磁性不對稱的主要貢獻來自錳酞花青分子在費米能階附近的自旋偏極化吸收態。
並列摘要
Organic Mn-phthalocyanine (MnPc) molecules are successfully deposited on the Cu(111) and Co/Cu(111) templates, and this can be verified from STM morphology. In addition, for MnPc/Co/Cu(111) system, all of the MnPc molecules are trapped on the surface of the Co nanoislands instead of Cu substrate. Furthermore, by using spin-polarized scanning tunneling microscopy and spectroscopy, the spin-polarized states of not only Co islands but also MnPc molecules have been resolved at 4.5K. And the major contribution of magnetic asymmetry of MnPc molecules comes from the spin-polarized absorption state of MnPc molecules near the Fermi energy.
