Rotational magnetocaloric effect in TbAl3(BO3)4 single crystal was predict by using measurements of the field dependences of magnetization and the temperature dependence of heat capacity. This effect has been modeled within the quasidublet approximation. The isothermal entropy changes, refrigerant capacity and adiabatic temperature changes were estimated. It was shown that the terbium aluminum borate may be a promising material for magnetic refrigeration.
