Magnetic, micromagnetic, and texture properties of the martensitic thin films prepared by magnetron sputtering of Ni-49.5 Mn-28 Ga-22.5 target on MgO(100) wafer are studied as a function of film thickness. The films exhibit 220-fiber texture. Moreover, in contrast to thick films, a considerable in-plane texture component is giving rise to the pronounced in-plane magnetic anisotropy found in the thin film. The texture features together with a large magnetocrystalline anisotropy lead to the particular domain structure and different magnetic anisotropy components of films depending on the film thickness and substrate nature.

Abstract
Magnetic, micromagnetic, and texture properties of the martensitic thin films prepared by magnetron sputtering of Ni-49.5 Mn-28 Ga-22.5 target on MgO(100) wafer are studied as a function of film thickness. The films exhibit 220-fiber texture. Moreover, in contrast to thick films, a considerable in-plane texture component is giving rise to the pronounced in-plane magnetic anisotropy found in the thin film. The texture features together with a large magnetocrystalline anisotropy lead to the particular domain structure and different magnetic anisotropy components of films depending on the film thickness and substrate nature.File in questo prodotto:
