Single crystal of yttrium aluminum borate YAl3(BO3)4 doped with chromium ions (1 at %) was studied using electron paramagnetic resonance spectroscopy. It is shown that chromium ions introduced into the sample occupy yttrium ion sites in the crystal structure. The parameters of the spin Hamiltonian of Cr3+ ions in the YАl3(ВО3)4 matrix are determined at different temperatures. The sign of the fine structure parameter D allows the conclusion that the chromium ions in YА13(ВО3)4 single crystals have an easy-plane anisotropy.
