FePt3 and CoPt3 compound nanoparticles were studied, magnetically and structurally. Compound ordering in crystal structure of these nanoparticles is formed at 600º C. Meanwhile, the shape and size of grains are prominent to be controlled. In this work, layers of FePt3 and CoPt3 nanoparticles with thicknesses of respectively 20 nm and 10 nm were fabricated on Si wafer, in L12 compound ordered phase. In these layers the size of nanoparticles were less than 10 nm according to Field Emission Scanning Electron Microscopy (FE-SEM) analyses. Direct synthesis method using sputtering system was applied. In order to orient nanoparticles, they were annealed, at 350º C and then cooled, in magnetic field of 30 mT. X-ray Diffraction (XRD) and Vibrating Sample Magnetometer (VSM) analyses showed crystalline, compound and directional ordering of these nanoparticles, respectively [ABSTRACT FROM AUTHOR] |
