Diffuse magnetic scattering from DHCP HoxCe1-x alloys

The magnetic ordering in HoxCe1-x alloys has been investigated by neutron d iffraction and X-ray magnetic resonant scattering (XMRS). The DHCP alloys d isplay a rich phase diagram, and highly unusual, diffuse neutron magnetic s cattering is observed over the composition range 0.35 less than or equal to x less than or equal to 0.5. The diffuse intensity may be the magnetic res ponse of the conduction band, and this interpretation is supported by the X MRS measurements, which show that there is hybridisation of the Ce 4f elect ron with the conduction electrons.
