1. A data carrier having an authenticity feature provided in the data carrier, comprising a magnetic feature which is personalizable under irradiation with a high-energy beam by changing physical and/or chemical properties wherein the magnetic feature is provided as a personalizable second-level feature in a functional layer, which feature is based on an opto-magnetic process which permits writing of information, such that macroscopically measurable magnetism is brought about at the irradiated location, wherein the magnetic feature comprises molecular magnets which have an organic or metal-organic base and are organized in sufficiently large one-dimensional to three-dimensional structures so that ferromagnetism or ferrimagnetism can arise.
