The well-known improvement of the layer-by-layer growth of ultrathin films of 3d ferromagnets by O surfactant is used to study the influence on their magnetism. X-ray magnetic circular dichroism (XMCD) reveals an induced magnetic moment of the O surfactant aligned in parallel to the 3d magnetization. In conjunction with density functional calculations we study the systematics of the x-ray absorption spectroscopy and XMCD at the O K edge.
