We report on the determination of element-specific magnetic order for
a 
mixed crystal by means of X-ray resonance exchange
scattering. For the first time, a different temperature dependence of
the sublattice magnetization of two lanthanide ions was observed. With
model calculations we were able to reproduce the measured temperature
dependence of the reduced sublattice magnetization. We can show that
competing magnetic interactions lead to the observed effects and can
reveal the frustration mechanism.
