A possible approach towards spin-polarized transport through single molecule magnets: Mn-12 on Au(100)/Fe(100)/MgO(100)

摘要

The possibility to use the Au(100)/Fe(100)/MgO(100) system as a substrate for future spin-polarized transport measurements on Mn-12 single molecule magnets has been investigated by means of scanning tunneling microscopy and X-ray photoelectron spectroscopy at room temperature. In particular, the stability of the iron layer during a wet chemical preparation of Mn-12 monolayers was studied. The results demonstrate that Mn-12 can be deposited on Au(100)/Fe(100)/MgO(100) while preserving the metallic nature of the ferromagnetic iron layer which is required as a possible source of spin-polarized electrons in future studies.
