A minuscule antenna which focuses a bundle of light is a technological development that has suddenly brought light-enabled magnetic storage of data within reach. In an article which appeared this week in Nano Letters, Radboud University physicist Theo Rasing demonstrates that magnetic switching with light is now possible on a surface area of just 40 nanometres. He did the research in an international team composed of members from Japan, Germany and the United States.
