New data on the ground state of impurity Ru3+ ions in the crystals of YAl3(BO3)4 and EuAl3(BO3)4 aluminum borates were obtained. It was shown that Ru3+ ion replaces trivalent rare-earth ions without breaking the symmetry of the site.The crystal field acting on 4d5 ions forms an EPR spectrum, which is described by the spin Hamiltonian with S¼1/2.
