Microscopically tiny ferromagnetic platelets exhibit a phenomenon which could be exploited in the future for particularly stable magnetic data storage: so-called magnetic vortex cores. These are needle-shaped magnetic structures measuring 20 nanometres (millionths of a millimetre) in diameter. Five years ago, researchers at the Max Planck Institute for Intelligent Systems in Stuttgart, Germany, found a [...]
