`Fe_(3)O_(4)`

Text Solution

Verified by Experts

The correct Answer is:
4
Ferrimagnetisms is observed when the magnetic moments of the domains in the substance are aligned (in an external magnetic field) in parallel and antiparalle directions in unequal numbers
`Fe_(3)O_(4)` (magnetite) and ferrites like `MgFeO_(4)` and `ZnFe_(2)O_(4)` are example of such substances.
