Neel, nay EHL, Louis-Eugene-Felix (1904-2000), a French physicist, made important discoveries in the field of magnetism. His work gave rise to such applications as the coating of magnetic recording tape and magnetic computer storage. Neel developed the concepts of antiferromagnetism and ferrimagnetism, which explain the magnetic properties of certain materials based on the arrangement of their atoms. For this work, Neel was awarded half of the 1970 Nobel Prize in physics. The other half went to Swedish physicist Hannes Alfven for unrelated work.
