Phys. Rev. Lett. 91, 227201 (2003) [4 pages]Induced Magnetic Ordering by Proton Irradiation in Graphite
See accompanying Physics Focus We provide evidence that proton irradiation of energy 2.25 MeV on highly oriented pyrolytic graphite samples triggers ferro- or ferrimagnetism. Measurements performed with a superconducting quantum interferometer device and magnetic force microscopy reveal that the magnetic ordering is stable at room temperature. © 2003 The American Physical Society URL:
