Magnetic and Dielectric materials in Material science – Study Material
We know that current through a circular coil produces magnetic moment along the axis of the coil. When the electrons revolve around the positive nucleus, orbital magnetic moment arises. Similarly when the electron spins, spin magnetic moment arises. Magnetism arises from the magnetic moment or magnetic dipole of the magnetic materials. Any material that can be magnetized by application of external magnetic field is called a magnetic material. For more details click the PDF link given below.

Anti Ferromagnetism :
In Antiferromagnetism, electron spin of neighbouring atoms are aligned anti parallel. Anti-ferromagnetic susceptibility is small and positive and it depends greatly on temperature.
Ferrites :
In a material of the magnitudes of permanent dipoles aligned antiparallel are not equal, such an uncompensated anti ferromagnetism is known as ferrimagnetism and the corresponding materials are said to be ferromagnetic or ferrites.
