| Outline of Final Research Achievements |
Magnetic circular dichroism in the hard x-ray region (HXMCD) is a suitable technique for realizing a bulk-sensitive magnetic microscope, because of relatively long penetration depth into materials and a good lateral resolution by using synchrotron radiation, and is actually used in recent microscopic researches on ferromagnetic materials. On the other hand, it has been known that the flipping ratio of HXMCD for 3d transition metal elements, such as Fe, Co and Ni, is very small, although these elements are important ones for magnetic materials. In this research, I have proposed a new magnetooptical effect in the hard x-ray region, which is called x-ray magnetic circularly polarized emission (XMCPE), and have experimentally confirmed the existence of XMCPE and remarkably large flipping ratio (about 20%) for a Fe specimen.
