Induced magnetic ordering by proton irradiation in graphite.
نویسندگان
چکیده
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.

Proton-induced magnetic order in carbon: SQUID measurements
In this work we have studied systematically the changes in the magnetic behavior of highly oriented pyrolytic graphite (HOPG) samples after proton irradiation in the MeV energy range. Superconducting quantum interferometer device (SQUID) results obtained from samples with thousands of localized spots of micrometer size as well on samples irradiated with a broad beam confirm previously reported ...
متن کاملMagnetism in Carbon: Writing Magnetic Structures with a Proton Micro-Beam on Graphite Surfaces
Recent publications demonstrated the generation of magnetic order at room temperature on graphite surfaces after irradiation with protons. In this contribution we show that it is possible to produce magnetic structures in the micrometer range using a proton micro-beam by proton irradiation of the surface of highly oriented pyrolytic graphite samples. The experimental results are compared with m...
متن کاملIrradiation-induced magnetism in graphite: a density functional study.
Recent experiments indicate that proton irradiation triggers ferromagnetism in originally nonmagnetic graphite samples while He ion bombardment has a much smaller effect. To understand the origin of irradiation-induced magnetism, we have performed spin-polarized density functional theory calculations of the magnetic properties of the defects which are most likely to appear under irradiation vac...
متن کاملInduced Magnetic Order by Ion Irradiation of Carbon-Based Structures
Irradiation effects in graphite were one major research area in the past, partially due to its application as a moderator in thermal nuclear reactors. Graphite is still a material of choice for nuclear applications due to its low cross-section for neutron absorption. The influence of irradiation damage produced by different kinds of ions on several properties of graphite was reviewed by Kelly (...

A comprehensive study on the effects of energetic protons on carbon fiber composites and compounds under consideration for use as low-Z pion production targets in future high power accelerators and lowimpedance collimating elements for intercepting TeV-level protons at the Large Hadron Collider has been undertaken addressing two key areas namely thermal shock absorption and resistance to irradi...
