Today (March 7, 1938) is the birthday of Albert Fert, the Nobel laureate who discovered the effect of magnetoresistance on hard disk memory in computers.
Albert Fert was born on March 7,
1938 in France. A French physicist. Fert graduated from the École Normale Supérieure in 1962 in
Paris, France. He then received his master's degree in 1963 from the University
of Paris. He then received his Ph.D. in 1970 from the University of South Paris
(Université Paris-Sud). He and the German physicist Peter Grünberg first
discovered a new physical effect in 1988 called the giant magnetosphere. This
effect results in the reduction of the electrical barrier magnitude when the
magnetic field is applied to a thin film of iron and chromium alternating. This
effect was discovered by Prof. Grünberg
in Germany during the same period as the benefit of self-examination.
He found that if there was a very
thin (~ 1 nanometer) non-ferrous magnetic film (for example chromium) between
two iron-magnetic films, the iron-magnetic films on either side would be
contacted by atomic magnetism, causing a magnetic flux in the opposite
direction between the iron magnets. Later, in 1988, he exaggerated this effect
by means of a thin layer of multilayer and discovered the effect of the giant
magnetometer (GMR). As a result, gigabytes of magnetic hard disk memory are
used in computers today. Regardless of this effect, the French physicist Albert
Fert discovered it alone at the University of South Paris (Universite de Paris
Sud).
The magnetic resistor effect is
used in the gigabyte magnetic hard disk memory used in computers today. The two
were awarded the 2007 Nobel Prize in Physics for their discovery. He is
currently a professor at the University of South Paris in Orsay, France. He is
also the director of a laboratory run jointly by the French Central Science
Laboratory and the Thales Group.
