On page 1034 W.-T. Pong, I. Manners, W.-Y. Wong, and co-workers report the simple and rapid fabrication of patterned L10-FePt alloy nanoparticles from a solution-processable bimetallic polyferroplatinyne polymer precursor. This approach holds great promise for fabricating L10-FePt-type bit-patterned media using high-throughput nanoimprint lithography, followed by controlled pyrolysis of the nanopatterned polymer. Each dot in the asgenerated FePt-containing nanodot array is magnetic, which can serve as a good platform for future ultrahigh-density perpen-dicular magnetic data recording systems.
