Question

What type of substances exhibit antiferromagnetism?

Answer 1

• When a substance is placed in a magnetic field then the electrons of that substance arranged themselves in an opposite direction, as a result, the net dipole moment becomes zero. These substances are known as antiferromagnetic substances and the process is called antiferromagnetism.
• 
• Antiferromagnetism is shown by transition elements.
• Examples of antiferromagnetic substances are Nickel oxide$\left(\mathrm{NiO}\right)$, Ferrous oxide$\left(\mathrm{FeO}\right)$, etc.
