(physics) Exhibiting antiferromagnetism.

(physics) In an antiferromagnetic manner

(physics) a phenomenon, similar to ferromagnetism, in which magnetic domains line up in a regular pattern, but with neighbouring electron spins pointing in opposite directions; materials showing this effect are either ferrimagnetic or diamagnetic, and become paramagnetic above the Neel temperature

(physics) An antiferromagnetic material

plural of antiferromagnet
