The structural and magnetic properties (field dependences of the magnetization in magnetic fields of up to 6 kOe) of thin-film Co 2 FeAl, and Co 2 NiSi Heusler alloys grown by pulsed laser deposition on glass and a single-crystalline Al 2 O 3 R-plane substrate at different growth temperatures (20, 280 and 420 °C) were studied. It was found that the stoichiometric composition of the films depends on the substrate temperature during growth and repeats the composition of the target for films grown at low temperatures. The films deposited on a single crystalline Al 2 O 3 substrate have uniaxial magnetic anisotropy in the plane.
