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

[edit]

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]
