N2 - Direct synthesis of tetragonal FePt nanoparticles in a robust TiO 2 matrix using a combined Sol-Gel/Pyrolysis Route was investigated. Absolute ethanol and 10% HNO3 were introduced in a argon flux into a two-necked flask pre-filled with argon for the hydrolysis of Ti(OEt) 4. The formation of metal nanoparticles proceeds was through the clustering of metal atoms inside the rigid and thermoresistant TiO2 network, which prevents their aggregation and permits them to convert into the desired L10 fct phase. Results show that the nanoparticles exhibit a mean size of 7.5 nm and are well isolated from one another due to the robust rutile matrix, in which they are embedded.
