| 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 micromagnetic simulations. |
