Atomically thin ferromagnetic and conducting electron systems are highly desirable for spintronics because they can be controlled with both magnetic and electric fields. We have fabricated and explored (SrRuO₃)₁–(SrTiO₃)₅ superlattices of exceptional quality. In these superlattices the active electron system comprises only a single RuO₂ plane. This atomically thin plane is found to be conducting and ferromagnetic.
