Within the international scientific community,
the number of times an article is quoted is an indication of the evaluation
of the quality of its research, its impact and formal proof of recognition.
The American Physical Society (APS ) has just published the latest results
of its "top ten most quoted articles," with CNRS physicists
and metallurgists taking top honors among their foreign colleagues. Two
CNRS studies in the area of physics are among the most quoted in internationally
renowned scientific publications.
In honor of the 50th anniversary of Physical Review Letters, the American
Physical Society has issued a classification of the ten most quoted articles
since the journal was first published. The article, " Giant Magnetoresistance
of (001)Fe/(001)Cr Magnetic Superlattices ," published in 1988, is
in sixth place with 2,455 quotes. It deals with the discovery of the giant
magnetoresistance effect (GMR) by Albert Fert's team at the Laboratoire
de Physique des Solides d’Orsay and the Thomson-CSF Central Research
Laboratory, a joint undertaking that led to the creation in 1995 of the
CNRS/Thales joint physics unit, part of the Université de Paris
Sud. In addition to its other applications, GMR is currently used to read
computer hard disks and is at the origin of electronic spin, the rapidly
growing research field that will have a major impact on information and
communication technologies.
The article, "Metallic phase with long-range orientational order
and no translational symmetry ," written with the participation of
Denis Gratias, researcher at the Laboratoire d’Etudes des Microstructures
(LEM, joint CNRS/ONERA physics unit), came in eighth place with 2,155
quotes. This article, written in 1984, marks the discovery of quasi-crystals,
paradoxal structures formed by atoms of some metal alloys, opening up
a new field of basic research in the areas of mathematics and crystallography.
These structures have many potential applications, particularly for coating
materials, as a result of their insulating properties.
