Abstract
The saturation magnetizations, local magnetic anisotropy field and coercivity values of FeCo film plated under various processing conditions have been investigated to optimize soft magnetic properties. Herein, we introduce a very promising processing technique based on the electrodeless deposition of FeCo film with carbohydrates as reducing agents. The produced FeCo film demonstrated significantly better saturation magnetization values and less contaminations, compared to those for the sample preparing with conventional reducing agent (sodium hypophosphite). The surface morphology and coercivities of FeCo films are dependent on the iron content and type of reducing agent. The coercive force values range from 12 up to 30 Oe and the saturation magnetization from 150 to 240 emu/g depending on the bath composition and deposition parameters. Maximum of saturation magnetization magnitude is reached for FeCo film with 30% cobalt. The local anisotropy field value of FeCo alloys increases with a decrease in Fe content for all reducing agent types.
Highlights
In recent decades, future green chemistry methods have been extensively investigated to replace energy-consuming methods of producing functional materials, which uses toxic substances in the synthesis process
Electrodeless deposition of FeCo alloys with different reducing agent was studied to determine how chemical and physical parameters affect the morphology of the deposited metal
In summary, the FeCo films were synthesized by electrodeless plating with arabinogalactan, starch and sucrose as nontoxic reducing agents
Summary
Future green chemistry methods have been extensively investigated to replace energy-consuming methods of producing functional materials, which uses toxic substances in the synthesis process. In 1998, Paul Anastas and John C. Warner published a set of principles to guide the practice of green chemistry [1].Recall some of them. The use of renewable material feedstocks and energy sources;the design of energy efficient processes. Chemical products should be designed to achieve their desired function while being as non-toxic as possible. Soft magnetic films have been widely used in the fields of magnetic recordings, magnetic sensors [2,3]
