New Developments in Ferrite Plating
نویسنده
چکیده
The ferrite plating a method synthesizing ferrite films from an aqueous solution -has developed lately as follows; (1) Applying power ultrasound to aqueous solution improves the qualities of ferrite coating on polymer microspheres much, (2) similarity is found between mechanisms of the ferrite plating and bacterial FesO4 ( magnetsome) synthesis, (3) using highly alkaline (pH=13) solution containing a chelating agent increases the solubilities of such particular ions as ~n"and ~ a ~ ' in ferrite-plated films , and (4) Fe30dCdS multilayer films are synthesized from a wet chemical process. Applications are proposed of ferrite-plated films to (5) backlayers for CoCr perpendicular magnetic recording media, (6) contrast agents for ultrasonography, and (7) catalyst for decomposing aqueous residual chlorine.

متن کاملMagnetic Thin Film Characterization
An improvement on the fabrication of magnetic thin films is currently on a level of intense research as these films are of great interest in the device industry. Some of these thin films posses high permeability and ferromagnetic resonance (FMR) frequency in the GHz range which are suitable for electromagnetic use. Methods for fabricating these films include sputtering, pulse laser deposition (...

Next generation magnetic microwave devices will be planar, smaller, weigh less, and perform well beyond the present state-of-the-art. For this to become a reality advances in ferrite materials must first be realized. These advances include self-bias magnetization, tunability of the magnetic anisotropy, low microwave loss, and volumetric and weight reduction. To achieve these goals one must turn...

Statement of the problem or situation that is being addressed typically, one to three sentences. New developments in the design of fixed-field alternating gradient (FFAG) synchrotrons have sparked interest in their use as rapid-cycling, high intensity accelerators of ions, protons, muons, and electrons. Compact RF cavities that tune rapidly over various frequency ranges are needed to provide th...
متن کاملSolute Trapped at Defects during the Displacive Formation of Bainitic Ferrite
New developments with bainite have resulted in a steel with an ultimate tensile strength of 2500 MPa, a hardness of 600-670 HV and a toughness in excess of 30-40 MPa m [1]. The novel microstructure is generated in a high carbon (0.98 wt.%) high silicon (1.46 wt.%) steel austenitized for 15 min. at 1000 oC, and then isothermally transformed at temperatures of ∼200 oC. Iron does not diffuse durin...
