...shares the physics prize with Alfvén for his penetrating research into magnetism. In the early 1930s, physicists explained that magnetism in materials like iron is caused by their electrons all spinning in the same direction. Neel contended that there was another form of magnetism in which the electrons of neighboring atoms whirled in opposite directions, thereby all but canceling out the observable field. The existence of this phenomenon, antiferromagnetism, was subsequently confirmed in such substances as manganese salts. Later, Néel discovered still another form of magnetism called ferrimagnetism, in which some of the spins...
