โœฆ Synopsis

We study the magnetic resonant X-ray scattering spectra around the Mn K-edge in RbMnF 3 on the basis of an ab initio band-structure calculation with including spin-orbit interaction. A resonant intensity from the dipolar (1s-4p) transition is obtained around the Mn 4p threshold only in the s2p 0 channel. Another peak about 4 eV below the 4p threshold is also obtained, but the intensity is too small compared with experiment. The contribution of the quadrupolar (1s-3d) transition is extremely small and there is no pre-edge peak.

We investigate the magnetic X-ray scattering spectra around the K-edge of Cu in antiferromagnetic KCuF 3 using an ab initio band-structure calculation based on the density-functional theory. By taking account of orbital polarization through the spin-orbit interaction, we obtain resonant enhancement

We present resonant magnetic X-ray scattering (RMXS) measurements in an applied magnetic field on a single crystal of Ca 3 Co 2 O 6 . We focus our attention on the transition from an incommensurate partially disordered antiferromagnetic state to a ferrimagnetic state: a lock-in and a divergence of t
