Computer hard drives and other devices use tiny particles of magnetic materials to store digital information. Technological advances require an increase in the density of information storage and therefore even smaller magnetic particles. This project has the potential to synthesise materials where a single molecule could act as the smallest possible unit of magnetic memory. The future application of these materials may provide an increase of three orders of magnitude in information storage density. In addition, they may find employment in quantum computers, which can perform calculations exponentially faster than conventional computers.Read moreRead less
