Powerful New Way to Control Magnetism: Colossal Magnetoelectricity Points the Way to Ultra-Dense Data Storage
A team of scientists at Rutgers University has found a material in which an electric field can control the overall magnetic properties of the material. If the magnetoelectric effect discovered by the Rutgers group can be extended to higher temperatures, it could be useful for manipulating small-scale magnetic bits in ultra high-density data storage.
