We present a systematic study of the electronic structure in A-site ordered manganites as function of doping and temperature. The energy dependencies observed with soft x-ray resonant diffraction (SXRD) at the Mn L_{2,3} edges are compared with struc

Geometrical frustration of the Fe ions in LuFe 2 O 4 leads to intricate charge and magnetic order and a strong magnetoelectric coupling. Using resonant x-ray diffraction at the Fe K edge, the anomalous scattering factors of both Fe sites are deduced

Soft x-ray resonant powder diffraction has been performed at the Mn ${L}_{2,3}$ edges of A-site-ordered ${\mathrm{SmBaMn}}_{2}{\mathrm{O}}_{6}$. The energy and polarization dependences of the (1/4 1/4 0) reflection provide direct evidence for a $({x}

PHYSICAL REVIEW B
Magnetic spiral structures can exhibit ferroelectric moments as recently demonstrated in various multiferroic materials. In such cases the helicity of the magnetic spiral is directly correlated with the direction of the ferroelectric moment and measu
