説明

<jats:p>We have investigated the in situ ordering process of sputtered FePt thin films deposited on heated substrates at 300 °C with different thicknesses. The films thinner than 50 nm were composed of nanograins (∼5 nm) of disordered FePt phase. Recrystallization occured when films were grown thicker than 100 nm, and transformation twins were observed in recrystallized grains, in which ordering to the L10 structure was confirmed.</jats:p>
