The chromium spin density wave: magnetic X-ray scattering studies with polarisation analysis

Low temperature magnetism of Cd-doped Ce2RhIn8 heavy fermion antiferromagnet

“…In principle, fits to the integrated intensities of all magnetic peaks can be used to determine the magnetic moment direction [23,[26][27][28][29]. However, in some cases the number and intensity of the measured magnetic peaks is not enough to unambiguously determine the direction of moment.…”

Magnetic and resonant X-ray scattering investigations of strongly correlated electron systems

“…The extrapolation to Q = 0 suggest a ratio of L /2 S = 0.14 ± 0.08 between orbital angular momentum and spin contributions to the magnetic moment [27]. The non-resonant X-ray scattering regime has also important applications in the domain of spin-density waves [29], charge density waves [30] or surface magnetism that exploits surface refraction effects of the charge scattering, in order to disentangle the magnetic and structural contributions from magnetic surfaces [31].…”

“…The Hannon's term in Eq. (29) can be rewritten in four distinct terms by using the previous relations and the dipole j r j and the quadrupole j i 2 r j (k · r j ) operators:…”

Resonant magnetic x-ray scattering spectra in spin-density-wave state of Cr fromab initioband structure calculations

“…In particular, magnetic diffraction techniques have been applied to various magnetic materials for studying the spin and orbital magnetic properties. [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18] In this paper we focus on the magnetic diffraction in the spin density wave (SDW) in chromium. 4,13 Chromium is a prototypical itinerant antiferromagnet forming a SDW state below the Néel temperature.…”
