What are the magnetic disordered materials?
Ferromagnetic material, antiferromagnetic material.

1. ferromagnetic materials: ferromagnetic materials have very strong magnetism, but the magnetism is short-range ordered, that is, the magnetic interaction between iron atoms is stronger than the long-range interaction.

2. Antiferromagnetic materials: The spins of atoms in antiferromagnetic materials are opposite, so the magnetism cancels each other, resulting in no net magnetism as a whole.
