A modified version of Haberland type gas aggregation source with an arrow-shaped aggregation chamber set with two magnetrons was used for the production of core@shell Ni@Ti nanoparticles. This configuration that had two separate magnetrons in one aggregation chamber gave the possibility to independently control the power to each magnetron and thus to control the structure of created nanoparticles.
Furthermore, the chosen geometry resulted, under optimized conditions, in the suppression of the formation of single-material nanoparticles that is a common problem in the case of conventionally used planar arrangement of magnetrons in the aggregation chamber.
