A General Strategy for Synthesizing FePt Nanowires and Nanorods

摘要

Synthesis of FePt nanoparticles with controlled shape and magnetic alignment has become an important goal in developing nanocrystal arrays for applications in information storage permanent-magnet nanocomposites,and catalysis.FePt alloys are chemically stable owing to the spin-orbit coupling and the hybridization between Fe 3d and Pt 5d states,and their magnetic properties can be tuned by simply controlling the atomic ratio of Fe and Pt in the alloy structure.
