Question

Is ${\mathrm{MgFe}}_2{\mathrm{O}}_4$ ferrimagnetic?

Answer 1

Explanation:

1. Ferrimagnetic substances- Ferrimagnetism is the permanent property of substances. A substance which shows ferrimagnetism is called a ferrimagnetic substance.
2. Ferrimagnetism is the magnetic property of materials having atomic moments aligned in opposite directions.
3. Ferrimagnetic substances are temperature-dependent.
4. ${\mathrm{MgFe}}_2{\mathrm{O}}_4$ is a ferrimagnetic substance but when the heat is provided, it becomes a paramagnetic substance.

Hence, ${\mathrm{MgFe}}_2{\mathrm{O}}_4$ is a ferrimagnetic substance.
