The work presents an experimental study of (Y, Gd)AlO₃:Mn²⁺ crystals grown by the Czochralski method under inert gas atmosphere and by the floating-zone method in the ambient air atmosphere. The Mn²⁺/Mn⁴⁺ ratio, the energy depth of the main dosimetric and shallow traps are analyzed in comparison with the YAlO₃:Mn²⁺ and (Y, Lu)AlO₃:Mn²⁺ crystals studied before.
