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.
Electromeric effect (1) The occurrence of movement of electrons from one atom to other in multi bonded atoms at the demand of attacking reagent is known as electromeric effect.
