  2007 (23rd) Japan Prize Laureates
Fert developed comprehensive, pioneering studies for a quantum mechanical understanding of electrical transport properties in ferromagnetic alloys.
Through his research, it became foreseeable in the mid-80's that the effect of spin-dependent scattering would give rise to magneto-resistance effects of unprecedented magnitude, provided one finds a means to switch the relative orientation of the magnetization of successive magnetic layers in a multi-layer from parallel to anti-parallel.
Fert's group discovered a GMR effect as large as 50% in a super-lattice consisting of 30 Fe/Cr bi-layers at low temperature (4.2K) by application of an external magnetic field of 1T.

 The CNRS has attributed Golden Medal to the physicist Albert Fert
Albert Fert marvels at many things: at landscapes from the Catalan Pyrenean mountains of his childhood, of course; at the genius of Thelonius Monk's music and Almodovar's films as well; and also, more pragmatically, at the purring noise of his computer hard disk.
An example of a significant contribution by Albert Fert to the theory of spin electronics is also the introduction of the spin accumulation concept, which today is used in many theoretical models.
Albert Fert and his team are hot on the trail to providing some answers to these questions.

Albert Fert's research in the field of nanosciences, and especially his discovery of giant magnetoresistance, has already had a major impact on information and communications technologies.
Albert Fert and the CNRS/Thales Joint Physics Unit have made a significant contribution to the development of spintronics, especially in the field of so-called spin transfer phenomena, which will have major applications such as the switching of magnetic memory devices and the construction of radiofrequency/hyperfrequency oscillators for professional electronics.
Albert Fert was born in Carcassonne on 7 March 1938.

 Two physicists keeps on winning international prizes
Peter Gruenberg, 67, of Germany and Albert Fert, 68, of France were digesting Tuesday the previous day's announcement that they had won one of five categories of the Wolf.
Such prizes are often seen as precursors to the Nobel Prize for Physics, the ultimate award in the field.
Gruenberg described last week how, working independently, he and Fert both discovered a phenomenon named giant magneto-resistance (GMR), and realized at a conference later in the same year, 1988, that the other had found it too.

 2007 Japan Prize in technology
This year’s Japan Prize in technology, awarded for breakthrough basic research with a high industrial impact, goes to Albert Fert and Peter Grünberg, who independently described giant magnetoresistance (GMR), in which the electrical resistance of certain materials drops when a magnetic field is applied.
Fert and Grünberg’s achievement is the independent discovery of Giant Magneto-Resistance (GMR) and its contribution to development of innovative spin-electronics devices.
From the 1970s onward, Fert developed comprehensive, pioneering studies for a quantum mechanical understanding of electrical transport properties in ferromagnetic alloys.

 GMR - Head Technology
The technology is named for the giant magnetoresistive effect, first discovered by two European researchers -- Peter Gruenberg and Albert Fert -- in the late 1980s.
While working with large magnetic fields and thin layers of magnetic materials, Gruenberg and Fert noticed very large resistance changes when these materials were subjected to magnetic fields.
This head is less expensive to produce, because it requires fewer process steps; and, it performs better in a drive, because the distance between the read and write elements is less.

 Giant-magnetoresistance pioneers win Wolf prize (January 2007) - News - PhysicsWeb
In 1988 research groups led by Fert and Gruenberg noticed that these materials display very large changes in their electrical resistance when exposed to a magnetic field – much larger than the magnetoresistance seen in other materials.
Albert Fert spent most of his career at the Université Paris-Sud in Orsay, where he did a PhD in physics in 1970 before becoming an assistant professor in 1970 and then professor of physics in 1976.
Fert and Gruenberg will share the $100 000 prize, which will be awarded later this year by the President of the State of Israel at the Knesset Building in Jerusalem.

 Articles - Giant magnetoresistive effect   (Site not responding. Last check: 2007-10-18)
The spin of the electrons of the nonmagnetic metal align parallel or antiparallel with an applied magnetic field in equal numbers, and therefore suffer less magnetic scattering when the magnetizations of the ferromagnetic layers are parallel.
The effect was first discovered in pure crystal layers in 1988 by Peter Grünberg of the Jülich Research Centre and Albert Fert of the University of Paris-Sud, working independently.
The possibilities of using the effect in a magnetic field sensor, and hence as a new type of reading head in a computer hard drive, were quickly recognised by an IBM research team led by Stuart Parkin, who replicated the effect in polycrystalline layers.

Then, in 1988, Albert Fert of the University of Paris in Orsay, France, discovered that this minor effect becomes quite major in the right materials.
The German research team, and later Fert, began to make multilayered films in which alternate layers were magnetized in opposite directions, says Levy.
Since Fert and Grunberg made those first GMR "short circuits," many other research groups have experimented with a wide range of combinations and internal magnetizations to make new GMR materials.

Grünberg's work laid the foundations for the field of spintronics, which exploits the quantum mechanical spin of electrons for micro- and nanoelectronics.
In their citation the jury emphasized that the basic research by Grünberg and Fert had provided "a major contribution to the advancement of information technology".
The Science and Technology Foundation of Japan, which awards the prize annually in two categories, said that the "their achievements are of inestimable importance and richly deserve their place in the annals of scientific discovery".

At a 1988 meeting in Le Creusot, France, three years after he'd begun the sputtering chamber experiments, Parkin heard a talk by Albert Fert, a University of Paris physicist who was measuring magnetoresistance, the change in electrical resistance of a metal in the presence of a magnetic field.
Along with Peter Grünberg, a colleague from the Institute of Solid State Research in Jülich, Germany, Fert had discovered that an iron-and-chromium sandwich produced a whopping magnetoresistance - so big it was dubbed giant magnetoresistance (GMR).
After Fert's talk, Parkin decided to try the same experiment back at IBM using his sputtering machine.

The "giant magnetoresistive" (GMR) effect was discovered in the late 1980s by two European scientists working independently: Peter Gruenberg of the KFA research institute in Julich, Germany, and Albert Fert of the University of Paris-Sud.
But he did not want to wait to use the expensive machine that could make multilayers in the same slow-and-perfect way that Gruenberg and Fert had.
Searching for a useful disk-drive sensor design that would operate at low magnetic fields, Bruce Gurney and colleagues began focusing on the simplest possible arrangement: two magnetic layers separated by a spacer layer chosen to ensure that the coupling between magnetic layers was weak, unlike previously made structures.
