A comparison of the magnetic properties of Proton- and Iron-implanted graphite

Abstract

In this work we have investigated the changes of the magnetic properties of highly oriented pyrolytic graphite samples after irradiation either with $\sim 3\times 10^{14}$ protons or $3.5\times 10^{13}...3.5\times 10^{14}$ iron ions with energies in the MeV range. Our results show that iron and proton irradiations can produce similar paramagnetic contributions depending on the implantation temperature. However, only protons induce a ferromagnetic effect.
