The Solid State


Give reason:
Ferrimagnetic substances show better magnetism than antiferromagnetic


In the presence of magnetic field, the magnetic moments of domains of an antiferromagnetic substances are ordered in such a way half of the magnetic moments are aligned in one direction while the remaining half is in opposite direction. As a result of it, a net magnetic moment will be zero whereas in case of ferrimagnetic substances the magnetic moments of the domains of ferrimagnetic substances are aligned in parallel and antiparallel directions in unequal numbers. As a result, there will be the small value of magnetic moment for ferrimagnetic substances.
