High substrate temperatures from 650 to 850 °C lead to the formation of the Mn<sub>5</sub>Ge<sub>3</sub> thin films with a low magnetization of ~250 kAm<sup>-1</sup>, which is an important characteristic for faster and low energy consumption of the switching of the magnetic orientation of magnetic thin films by spin-transfer torque. The highest temperature conducts to the formation of the Mn<sub>5</sub>Ge<sub>3</sub> phase with only a small amount of Mn<sub>5</sub>Ge<sub>2</sub> hexagonal clusters. Additionally, carbon doping of the Mn<sub>5</sub>Ge<sub>3</sub> sample grown at 750 °C exhibits an enhancement of the Curie temperature from 296 K to 390 K. The growth mechanism corresponds to a Volmer-Weber mode. ER -
