Heusler type Ni2MnGa is a ferromagnetic shape memory alloy. Martensitic transformation occurs within the ferromagnetic temperature range. Ni2MnGa films were fabricated by the melt spinning method and the sputtering method. The physical properties, such as transformation temperatures and magnetic behaviors, of these films was studied. These films had good crystallinity with preferred orientation and showed the crystal structure as same as bulk specimen. Rapidly solidified Ni2MnGa films made by the single roll melt spinning method have 20μm in thickness and 1 mm in width. Sputtered Ni2MnGa films were made by using a high frequency magnetron sputtering apparatus. The thickness of the film was 5μm. The films which were deposited on the poly-vinyl alcohol substrate showed shape memory effect.
