Question

What is meant by ‘antiferromagnetism’ ?

Answer 1

In materials that exhibit antiferromagnetism, the magnetic moments of atoms or molecules, usually related to the spins of electrons, align in a regular pattern with neighboring spins (on different sublattices) pointing in opposite directions is called antiferromagnetism.

Answer 2

${\bf{Antiferromagnetism:-}}$

Substances in which domain structure are similar to ferromagnetic substances but are oriented to oppositely, which cancel the magnetic property are called antiferromagnetic substances
