Determine about the Antiferromagnetic materials
Antiferromagnetic materials are materials in which almost all magnetic dipoles are linked up antiparallel to each other. Its susceptibility increases with increase in temperature, until a critical temperature is reached, beyond which it becomes paramagnetic. A number of the materials are MnF2, MnO2, MnS. These too are rarely used in electrical application.
