Single crystals Tb1–x Ho x Al3(BO3)4 with x = 0, 0.1, 0.5, 0.9, 1 have been grown based on bismuth trimolybdate using a solution–melt method. Their magnetic properties have been studied in the temperature range of 4.2–295 K and magnetic fields to 9 T. The effective magnetic moments μeff|| and μeff⊥ have been determined. It has been found that the temperature dependence of the susceptibility measured experimentally differs from that calculated on the assumption that the contributions of Tb3+ and Ho3+ ions are proportional to fractions from the susceptibilities of TbAl3(BO3)4 and HoAl3(BO3)4, respectively.
