Outline of Final Research Achievements

We developed a new laser excited magnetic circular dichroism scanning tunneling microscopy, which detected the signal difference by applying circular polarized lights, for observing the magnetic domains of the sample surface. Additionally, we observed the magnetic property of iron phthalocyanine thin films on metal surface by means of in-situ X-ray magnetic circular dichroism at Beamline 4B of UVSOR-III.The XMCD result suggests that the electronic state of iron phthalocyanine on the Co layer is modified by strong interaction between the molecule and the Co layer and the presence of a ferromagnetic exchange coupling between the Fe atom in the molecular and the Co atom in the underlying layer.
