Ferromagnetic FePt nanoparticles formed in Al2O3 by ion implantation
Description
Oriented, ferromagnetic FePt nanoparticles have been produced in Al2O3 single crystals by ion implantation and annealing. FePt orientation and particle size depends strongly on the implantation conditions. Magnetic coercivities of these nanocomposites are extremely high, reaching values in excess of 20 kOe for Pt concentrations of ∼45% in the FePt alloy. The formation of ferromagnetic FePt nanoparticles in fused SiO2 is also demonstrated
