The study of the interaction between organometallic phtalocyanines and magnetic metals has attracted interest due to its application in the field of spintronics. Most of the studies were focused on the magnetic properties of these metal-organic complexes coupled to ferromagnetic and antiferromagnetic metallic surfaces [1]. In the present work we study the interaction between the organic layer and ferromagnetic semiconducting/insulating substrates, in particular EuS and CrSiTe3. EuS is a 3D material where all the neighbours interact magnetically, whereas CrSiTe3 is a laminar material where magnetic interactions are confined in the plane and has been proposed as candidate single-layer ferromagnetic semiconductor.
Using a multi-technique surface science approach, combining XPS, LEED, XAS and XMCD, we analyze the coupling of the organic layer and its effect on the magnetic response of the system.
