Small Objects of attraction

Having understood the physics behind these minute magnetic particles, it soon became apparent to Russell that they could be used as logic gates for a microprocessor. The team has already demonstrated the capability of such structures to work as a single logic gate, and the next step will be to develop the technology to produce a complete working device.

"You can think of this as being similar to the invention of the first transistor", explains Russell Cowburn. "Once you have demonstrated that one works, then more complex circuits can be built and the technology takes off."

Although the research to produce these nanoscale magnets is highly fundamental, the team are now looking for industrial links, especially with potential manufacturers.
