Abstract
Recently, rapid improvement and miniaturization have been in progress in electronic devices. Integration of thin film magnetic core with high magnetic saturation, uniaxial anisotropy and high resistivity in electronic circuit can meet the demand for lighter, faster and smarter devices with high computing and communication functionalities in miniaturized packages. On the increasing demands for soft magnetic nanofilms in miniaturized electronic devices, this research mainly focuses on development of such soft magnetic nanofilms assembled by the energetic impact of Fe-Fe3O4 nanoparticles. The research presents the study on “Soft magnetic nanofilms assembled from the energetic impact of Fe-Fe3O4 core shell nanoparticles on the tilted substrates which help us to create excellent uniaxial anisotropy with high magnetic saturation and high resistivity and can contribute to the development of soft magnetic materials for next generation wireless network”.The Iron/Iron-oxide (Fe-Fe3O4 ) core shell soft magnetic nanofilms are produced by the cluster deposition technique. The Fe-Fe3O4 core shell nanoparticles were accelerated to the silicon substrate tilted at different oblique angels (15, 30, 60 and 90 degree) with respect to the incident beam provided with the potential 0, 2.5 and 5 kV. The nanoparticles are allowed to deposit with the high energy impact on the silicon substrates tilted at different angles to induce uniaxial shape anisotropy at room temperature as the shape of the particle changes from spherical to ellipsoidal. The oblique angle dependence of the different properties like structural, magnetic, and electrical properties of the magnetic nanofilms have been investigated in this paper. The sample prepared at a 30-degree angle and at 5 kV potential exhibits the soft magnetic properties with magnetic saturation of 138 emu/g, low coercive field of 10 Oe, electrical resistivity of 187 .cm and uniaxial anisotropy field of 180 Oe.
