copper thin films with nano-scale structure have numerous applications in modern technology.  in this work, cu thin films with different thicknesses from 50–220 nm have been deposited on glass substrate by dc magnetron sputtering technique at room temperature in pure ar gas. the sputtering time was considered in 4, 8, 12 and 16 min, respectively. the thickness effect on the structural, morpholo...

Recent experimental developments on the electric field effect on magnetism in metallic magnetic materials are reviewed. The change in the electron density at the surface of metallic ultra-thin magnets by the application of an electric field results in modulations of the Curie temperature, magnetic moment, magnetic anisotropy, and domain wall velocity. The study focused on this paper is the elec...

Isotropic magnetic materials with high resonant frequencies are useful for applications in microwave devices. Undoped CoFe thin films, as common soft magnetic materials with high saturation magnetization, show isotropic characteristics but no high frequency response. Here, we use ferrite doped CoFe thin film to realize a resonant frequency higher than 4.5 GHz at all orientations. The exchange c...

We describe a new type of magnetometer based on a microelectromechanical system (MEMS) for in situ monitoring of magnetic film moment during the film deposition process. The magnetometer measures mechanical torque on a film as it is deposited onto a microscopic flexible silicon cantilever. The cantilever is excited by an external ac magnetic field and its angular displacement is proportional to...
