French physicist
Louis Eugène Félix Néel ForMemRS (22 November 1904 – 17 November 2000) was a French physicist born in Lyon [ 5] who received the Nobel Prize for Physics in 1970 for his studies of the magnetic properties of solids .[ 1]
Biography
Néel studied at the Lycée du Parc in Lyon and was accepted at the École Normale Supérieure in Paris . He obtained the degree of Doctor of Science at the University of Strasbourg . He was corecipient (with the Swedish astrophysicist Hannes Alfvén ) of the Nobel Prize for Physics in 1970 for his pioneering studies of the magnetic properties of solids .[ 6] His contributions to solid state physics have found numerous useful applications, particularly in the development of improved computer memory units. About 1930 he suggested that a new form of magnetic behavior might exist; called antiferromagnetism , as opposed to ferromagnetism .[ 7] Above a certain temperature (the Néel temperature ) this behaviour stops. Néel pointed out (1948)[ 8] that materials could also exist showing ferrimagnetism . Néel has also given an explanation of the weak magnetism of certain rocks, making possible the study of the history of Earth's magnetic field .[ 9] [ 10] [ 11] [ 12] [ 13] [ 14] [ 15] [ 16] [ 17]
He is the instigator of the Polygone Scientifique in Grenoble .[citation needed ]
The Louis Néel Medal , awarded annually by the European Geophysical Society , is named in Néel's honour.[citation needed ]
Néel died at Brive-la-Gaillarde on 17 November 2000 at the age 95, just 5 days short of his 96th birthday.[citation needed ]
Awards and honours
Néel received numerous awards and honours for his work including:
Awards
Distinctions
Owing to his involvement in national defense, particularly through research in the protection of warships by demagnetization against magnetic mines, he received numerous distinctions:
