- Magnetic moments of the domains in the substance are aligned in parallel and anti-parallel directions in unequal numbers.
- They are weakly attracted by magnetic field as compared to ferromagnetic substances.
- For example, Fe3O4 (magnetite) and ferrites like MgFe2O4 and ZnFe2O4.
- These substances also lose ferrimagnetism on heating and become paramagnetic.
