PF Seminar DATE: 2004-11-04 10:00 - 11:00 PLACE: PF Kenkyuto Biulding 2F Conference Room TITLE: PF Seminar Diffraction physics with polarized x-rays:Recent developments and current challenges SPEAKER: Dr. C. Detlefs   (European Synchrotron Radiation Facility, Grenoble ) LANGUAGE: English URL: http://pfwww.kek.jp/pf-seminar/ ABSTRACT: Although linear polarization analysis of the diffracted x-ray beam has become a routine method, especially in magnetic x-ray scattering, experimental conditions are still far away from perfection. This is even more true for the use of x-ray phase plates, which may be employed to change the polarization of the incident beam. 　This talk will discuss recent developments on the technical, experimental and　theoretical side, and it will outline the remaining challenges that need to be addressed in the near future. To show an example where x-ray diffraction with polarization analysis significantly improved our understanding of a sample, I will present our recent results on NpO2. Back
