Definition
Proper noun A French surname, most notably belonging to Louis Eugène Félix Néel (1904–2000), a French physicist who won the Nobel Prize in Physics in 1970 for his fundamental research and discoveries concerning antiferromagnetism and ferrimagnetism.
Usage
- The word "Neel" is used almost exclusively as a proper noun to refer to the physicist Louis Néel or, by extension, to physical concepts and awards named after him.
- It is capitalized.
Examples
- Neel received the Nobel Prize for his explanation of antiferromagnetism.
- The Neel temperature is a critical point in certain magnetic materials.
- The university established a chair in honor of Neel.
Advanced Usage & Related Concepts
- Neel temperature (T_N): The temperature above which an antiferromagnetic material becomes paramagnetic.
- Neel wall: A type of domain wall in thin magnetic films.
- Neel point: Synonym for Neel temperature.
- Antiferromagnetism: A type of magnetic ordering, theoretically predicted and explained by Louis Néel, where adjacent atomic dipoles align in opposite directions, resulting in no net macroscopic magnetization.
Variants and Related Words
- Néel: The correct spelling of the surname includes an acute accent on the first 'e'. In English texts, the accent is sometimes omitted.
- Neelian: An extremely rare adjective form meaning "of or relating to Louis Néel or his work."

- "Neel" is not a common English word outside of this scientific and biographical context. It should not be confused with the similar-sounding word "kneel."
- Its primary dictionary entry is as a proper noun referring to a specific individual whose work had a significant impact on solid-state physics.
Noun
- French physicist noted for research on magnetism (born in 1904)
