title = "Ferromagnetic carbon materials prepared from polyacrylonitrile",
abstract = "We report a ferromagnetic carbon material that is attracted by a permanent magnet. The ferromagnetic carbon material was prepared by pyrolysis of polyacrylonitrile at 1273 K for 1 h. Chemical analysis combined with an energy-dispersive x-ray analysis revealed that the carbon material did not contain any transition metals. The metal-free ferromagnetic carbon material exhibited a saturation magnetization of 1.22 emu/g at room temperature.",
