Magnetic Materials

Neel temperature

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

Magnetic Materials

Spontaneous magnetization

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

Magnetic Materials

Ferrimagnetic materials

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
