Using element-specific X-ray magnetic circular dichroism (XMCD) technique we have studied different magnetic sublattices in a multiferroic Ho0.5Nd0.5Fe3(BO3)4 single crystal. The XMCD measurements at the L2,3-edges of Ho and Nd, and at the Fe K-edge have been performed at T=2~K under a magnetic field up to 17~T applied along the trigonal c-axis as well as in the basal ab-plane. All three magnetic sublattices are shown to undergo a spin-reorientation transition under magnetic field applied along the c-axis. On the contrary, when magnetic field is applied in the ab-plane only the holmium atoms exhibit a magnetization jump. Thus, the element-specific magnetization curves revealed the Ho sublattice to be much stronger coupled to the Fe one than the Nd sublattice. The results demonstrate that the Ho3+ subsystem plays even more dominant role in magnetic behavior of Ho0.5Nd0.5Fe3(BO3)4 crystal than in pure HoFe3(BO3)4 crystal.
