The value of the magnetic moment is zero in the case of antiferromagnetic substances because the domains ________.
(i) get oriented in the direction of the applied magnetic field.
(ii) get oriented opposite to the direction of the applied magnetic field.
(iii) are oppositely oriented with respect to each other without the application of the magnetic field.
(iv) cancel out each other’s magnetic moment.
Answers (2)
The answer is the option (iii, iv) In the case of antiferromagnetic substances like manganese oxide, the magnetic moment becomes zero because the magnetic moments of atoms align in a pattern with neighbouring spins pointing in opposite directions which cancel out each other resulting in 0 net dipole moment.
