Recently, chemical and physicochemical methods have been successfully used to make Fe-Pt nanoparticles, thin films. This paper reported another physicochemical method, namely sonoelectrodeposition, to produce Fe-Pt nanoparticles. In the sonoelectrodeposition, the electrodeposition process was assisted with a sonicator. The Ti horn of the sonicator played a role as the cathode on which Fe-Pt nanoparticles were deposited. After a certain time of deposition, a sonic pulse was applied to remove the particles from the Ti cathode. The composition of Fe-Pt particles can be controlled by changing the concentration of Fe a...
