| Research Abstract |
Lensless Fourier transform holography measurement using hard X-rays was developed to observe the magnetic domain structure in bit-patterned media for ultradense data recording, with a sub-10-nm spatial resolution. This technique used the coherence and polarization properties of synchrotron X-rays. A charge density image of the magnetic dots made of Co/Pt multilayer was successfully obtained with a 30-nm resolution. Magnetic imaging has been done but the statistical accuracy should be improved. Refinements in the experimental arrangement and analysis method are ongoing.
