FePt nanoparticles with a carbon coating are obtained through hydrothermal treatment of iron and platinum precursors in a glucose solution. The hydrothermal treatment and subsequent calcination produces thermally stable fullerene-like carbon nanoparticles that encapsulate or decorate the FePt particles with sizes of ca. 5 nm (see figure). No severe macroscopic particle coalescence is observed from these coated particles.
