Is it true that the electronic relationship between Fe2+ and Fe3+ in magnetite causes ferrimagnetism rather than diamagnetism?

Magnetite (Fe3O4) is a classic example of a ferrimagnetic material due to the exchange interactions between its Fe2+ and Fe3+ ions, making this relationship common knowledge that requires no citation.
