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.

Magnetite - Iron Oxide is available in black.
Magnetite is an oxide of iron which occurs in igneous rocks, and in veins and replacement deposits; it is one of the most important ores of iron. It usually occurs as a coarse, granular mass of black octahedral crystals, and produces a black streak. Magnetite is permanently magnetic, and was the first magnetic material to be discovered, known then as lodestone.
It is known as Iron(II,III) Oxide or Ferrous-Ferric Oxide, but its IUPAC name isIron(II) Di-iron(III) Oxide. It has the formula FeO.Fe2O3 but it is generally known as Fe3O4. It is formed by chemical combination of Iron(II) Oxide with Iron(III) Oxide. It has a special property different from the other 2 oxides, as it is exhibits Magnetism. It exists naturally in the Earth in form of Magnetite (or Lodestone) mineral. Some similar Compounds are Mn3O4, Pb3O4 etc.When iron is molten it reacts with water (vapor) to form [Fe3O4]3 Fe + 4 H2O ----> Fe3O4 +4 H2It can also be prepared by reduction of Iron(III) Oxide using Hydrogen(H2) or Carbon Monoxide(CO)3 Fe2O3 + H2 ----> 2 Fe3O4 + H2Oor3 Fe2O3 + CO ---->2 Fe3O4 + CO2
The mineral magnetite is also known as lodestone, a name also used for pieces of the ore that are natural magnets. Magnetite consists of iron (II,III) oxide with the formula Fe3O4.

Lodestone is Fe3O4-also called magnetite.

Magnetite is Iron and Oxygen. So no, it is considered an oxide.

No. Magnetite is the compound iron II, III oxide, Fe3O4
