Ever since the first hard drives were created, research has been conducted to find ways of recording an increasing amount of data in increasingly small spaces at an increasingly fast pace. What is new, say researchers working on the data storage of the future at the Institut Jean Lamour in Nancy and the Centre de Nanosciences et de Nanotechnologies in Saclay, is the need to save energy to combat global warming. CNRS scientists are assembling iron, cobalt and nickel atoms to create nanomaterials that can improve tomorrow’s magnetic memories. The applications of this research are eagerly awaited by industrialists who have to cope with an increasing volume of data against the backdrop of a serious environmental issue.
