Fert, Albert

(älbâr` fâr), 1938– French physicist, b. Carcassonne, France. After receiving his Ph.D. at the Univ. of Paris-Sud in 1970 Fert accepted a teaching position there and headed a research group, becoming a professor in 1976. In 1988 he discovered a physical effect he named giant magnetoresistance (GMR) because tiny changes in a magnetic field produced large changes in electrical resistance. For this discovery, which gave rise to the field of spintronicsspintronics,
 spin electronics,
or magnetoelectronics,
science and technology that harnesses the spin state of electrons in addition to the electrical charge state to store data or perform calculations.
