X-Ray Magnetic Absorption and Scattering (XMAS)

1 . Introduction Understanding of magnetic property and structure in magnetic materials forms a wide field of research interesting not only from a fundamental point but also from a practical point. Advantages in brilliance and polarization of 3rd generation synchrotron radiation (SR) open out a new field in magnetism differing from neutron magnetic scattering. In particular, this is characterized by separation of spin and orbital features, high k-resolution, and resonant enhancement. For the purpose of such research, spectroscopy and diffractometry using linearly or circularly polarized X-rays are useful technique and will be realized on BL39XU in the photon energy range from 5 to 25 keV. This end station is composed mainly of a diffractometer and a phase retarder assembly.
