Magnetic properties of materials

In magnetite, each iron atom in a unit cell contributes to the magnetic moment, but one has a different valency than the others (two Fe 3+ and one Fe 2+). The Fe 3+ atoms align to oppose each other, canceling each other out, but the Fe 2+ is free to align with an external magnetic field.
