O Prêmio Nobel de Física de 2007 foi concedido para os físicos Albert Fert da Unité Mixte de Physique CNRS/ THALES, Université Paris-Sud e para Peter Grünberg de Forschungszentrum Jülich GmbH pela descoberta do efeito de Magnetoresistência Gigante, cuja tecnologia associada é utilizada na leitura de discos rígidos de computadores.

Segundo o site oficial do prêmio: "In 1988 the Frenchman Albert Fert and the German Peter Grünberg each independently discovered a totally new physical effect – Giant Magnetoresistance or GMR. Very weak magnetic changes give rise to major differences in electrical resistance in a GMR system. A system of this kind is the perfect tool for reading data from hard disks when information registered magnetically has to be converted to electric current. Soon researchers and engineers began work to enable use of the effect in read-out heads. In 1997 the first read-out head based on the GMR effect was launched and this soon became the standard technology. Even the most recent read-out techniques of today are further developments of GMR."

Os artigos originais desta descoberta são: O interessante, para nós tupiniquins, é que o PRL do primeiro artigo tem como primeiro autor o físico brasileiro M. N. Baibich.
