Albert Fert found that layering magnetic and non-magnetic metals just right could swing electrical resistance wildly — giant magnetoresistance, the trick that let hard drives pack gigabytes where kilobytes used to live.

Biography

About

Born 7 March 1938, Fert spent his career in French physics labs, working the boundary between magnetism and electronics. The breakthrough came when he discovered giant magnetoresistance, a phenomenon where thin-film structures of alternating magnetic materials changed their resistance dramatically under magnetic fields. That finding, made independently alongside Peter Grünberg, became the engine of modern hard disk density — suddenly you could read microscopic bits reliably, and storage exploded. The Nobel came in 2007. He went on to hold posts at Paris-Saclay University, direct a joint CNRS-T…
