Europium (II) sulfide is the inorganic compound with the chemical formula EuS. It is a black air-stable powder. Europium possesses an oxidation state of +II in europium sulfide whereas the lanthanides exhibit a typical oxidation state of +III. Its Curie temperature (Tc) is 16.6 K. Below this temperature EuS behaves like a ferromagnetic compound and above it exhibits simple paramagnetic properties. EuS is stable up to 500 °C in air when it begins to show signs of oxidation.
