The project results related to our finding of nanotwinning in Ni-Mn-Ga were presented at Esomat International conference in Metz, France in oral and by poster (see below). We show that the material becomes nanotwinned for certain ranges of composition and temperature. As the nanotwinning distorts the relation between the crystal lattice and the X-ray diffraction pattern, the finding is very important for any further structural studies of Ni-Mn-Ga Heusler alloys. Moreover the properties of the material are presumably influenced by the nanotwinning, which will be further investigated in future.
