| Outline of Final Research Achievements |
In this proposal, we have developed fluorescence-yield depth-resolved x-ray magnetic circular dichroism (XMCD) measurement system by using soft x-ray camera, and performed a study on the multiferroicity at the ferromagnet/insulator junction. By placing the permanent magnet next to the sample and irradiating the circularly polarized synchrotron soft x ray on it, the depth-resolved XMCD measurement under the magnetic field has been realized. Its depth resolution is estimated to be sub nm. We furthermore developed the sample holder so that the depth-resolved XMCD measurement under the electric field has realised, as well.
