Resonant X-ray Scattering Study of Magnetic and Electric-quadrupole Order in U${}_{0.75}$Np${}_{0.25}$O${}_2$

S. B. Wilkins, J. A. Paxiao, R. Caciuffo +7

We have used element specific X-ray resonant scattering to investigate the M edge resonances in a single crystal of \unpo. Earlier neutron diffraction and Mössbauer studies had sho…
