To explain the phenomenon of ferromagnetism, Weiss proposed a hypothetical concept of ferromagnetic domains. He postulated that the neighboring atoms of the ferromagnetic materials, due
Domain is a region in a ferromagnetic material where all the magnetic dipole moments are aligned. The domains are of microscopic size of the order
The susceptibility of antiferromagnetic materials are small and positive. It increases with the rise in temperature. The susceptibility becomes maximum at Neel temperature and decreases
The magnetisation of antiferromagnetic materials depends on temperature. The magnetisation increases with the rise in temperature and becomes maximum at a particular temperature. Above this
In the presence of the strong magnetic field, antiferromagnetic materials are weakly magnetised in the direction the field. This property of the materials is called
In the presence of the strong magnetic field, antiferromagnetic materials are weakly magnetised in the direction the field. This property of the materials is called
Antiferromagnetism was first discovered by Neel and Bitter and later extended by Van Vleck. Experimentally, antiferromagnetism was first observed as a property of MnO by

The ferromagnetic materials possess magnetic moment and thus magnetization even in the absence of the applied magnetic field, this magnetization is known as the spontaneous
In ferrimagnetic materials, the magnetic moments of unequal magnitude are aligned in opposite directions so that net magnetisation occurs. According to Neel, ferrimagnetism is the
