It stands for the charge on the iron ion. In Iron III oxide iron has a 3+ charge.
The name of the compound Fe3O4 is called iron (II,III) oxide. (Wikipedia)
iron (III) oxide
FeO for ferrous oxide, ( iron(II) oxide); Fe2O3 for ferric oxide, (iron(III) oxide) and Fe3O4 for ferrous ferric oxide, (iron (II,III) oxide)
Actually there are several iron oxides, iron(II)oxide, iron(III)oxide and iron(II,III)oxide, and iron(III)oxide comes in four so-called 'phases'.All of these are compounds of iron with oxygen.
The iron oxide with the formula F3O4, called iron (II,III) oxide, is known as magnetite. There are also iron (II) oxide, FeO, and iron (III) oxide, Fe2O3, but they are not magnetite.
