Abstract

Special features of the formation of the defect and impurity states of diamond single crystals grown in the Fe–Mg–Al–C growth system by the temperature gradient method at the pressure 7.2–8.2 GPa and temperature 1700–1900°C have been investigated. It has been shown that as the magnesium content of the growth system increases, the type of the grown crystals changes in the following sequence: IIa → IIb.
