How Does Magnetic Materials Work?

These materials have small regions where the magnetic moment can be directed within a specific direction 

called magnetic domains which are responsible mainly for the exclusive performance of materials. The

 materials’ complete energy can be contributed simply by the anisotropy energy, exchange energy & 

magnetostatic energy. Whenever the magnetic material’s size is reduced, then it enhances various domains in 

the material. So due to the reduction within magneto-static energy, more domain walls will increase exchange 

& anisotropy energy. Thus, the size of the domain will decide the magnetic material’s nature.

The magnetic moment is not steady for some materials that have smaller particle diameters as compared to 

the critical superparamagnetism diameter. Whenever the diameter of the particle is between the critical diameter 

of superparamagnetism & single domain, then the magnetic moment will become stable.
