The magnetism of a DHCP Ho-Ce alloy has been investigated using X-ray magne
tic resonant scattering. A self-consistent magnetic structure is proposed t
hat agrees with diffraction data for three different cross sections (neutro
n, dipolar and quadrupolar). The spectroscopic valence of the Cc is found t
o be 3.27(5), and the Ce is in an intermediate-valence state in this alloy.
