Resumen
In this work we use resonant x-ray diffraction combined with polarization analysis of the diffracted beam to study the magnetic ordering in EuTePbTe multilayers. The presence of satellites at the (1/2 1/2 1/2) magnetic reflection of a 50 repetition EuTePbTe superlattice demonstrated the existence of magnetic correlations among the alternated EuTe layers. The behavior of the satellites intensity as T increases toward the Ǹel temperature TN indicates that these correlations persist nearly up to TN and suggests the preferential decrease of the magnetic order parameter of external monolayers of each EuTe layer within the superlattice. © 2008 American Institute of Physics. 92 24
