Which type of magnetism will be shown by hematite?

Antiferromagnetism

Hematite shows 4. antiferromagnetism.

Antiferromagnetism is a type of magnetism in which the magnetic moments of neighboring atoms are aligned in opposite directions. This cancels out the net magnetic moment of the material, making it overall non-magnetic.

Hematite is an iron oxide mineral with the formula Fe₂O₃. It is the most common form of iron oxide and is found in many different colors, including red, brown, and black. Hematite is a good conductor of heat and electricity and is used in a variety of applications, including jewelry, magnets, and pigments.

Paramagnetism is a type of magnetism in which the magnetic moments of neighboring atoms are aligned in the same direction, but the alignment is not permanent. This means that the material can be magnetized by an external magnetic field, but the magnetism will disappear when the field is removed.

Diamagnetism is a type of magnetism in which the magnetic moments of neighboring atoms are aligned in opposite directions, but the alignment is not as strong as in antiferromagnetism. This means that the material is weakly repelled by a magnetic field.

Ferromagnetism is a type of magnetism in which the magnetic moments of neighboring atoms are aligned in the same direction and the alignment is permanent. This means that the material is strongly attracted to a magnetic field and can be magnetized even without an external field.
