| Research Abstract |
We have investigated magnetic properties and electronic structures of organic magnetic thin films on various surfaces by using ultrafast pulsed laser and synchrotron radiation. In case of manganese phthalocyanine known as organic magnets on ferromagnetic metal substrates, the magnetization behavior of the only first layer at the interface is same as the ferromagnetic substrate. We have constructed a system for two-photon photoemission spectroscopy and magnetic circular dichroism. By using this system, we have revealed the occupied and unoccupied electronic structure of manganese phthalocyanine thin films. Furthermore the system enable us to observe the ultrafast electron dynamics in the organic magnetic thin films with 200 fs time resolution.
