$iv$. Antiferromagnetism
(N/A) $iv$. Antiferromagnetism: Antiferromagnetic substances have domain structures similar to ferromagnetic substances,but are oppositely-oriented.
The oppositely-oriented domains cancel out each other's magnetic moments,resulting in a net magnetic moment of zero.
Example: $MnO$ (Manganese$(II)$ oxide).
Schematic alignment of magnetic moments in antiferromagnetic substances:
