Thank you very much for reading my question.
I am interested in magnetic thin layer with easy magnetic axis perpendicular to the plane of the layer, it is also called "out of plane anisotropy" , "perpendicular magnetic anisotropy" and the like. In the literature I know there plenty of examples employing MgO as substrate, I do not know if there is any particular reason for this. I would like to know if these layers can be grown, specially by PVD on Al substrates. In some cases the contact between both materials at the interface is critical, so perhaps MgO can not be replaced, I am not sure. On the other hand, the PMA can also be due to the crystalline structure of the magnetic material, I guess that in thaose cases an Al substrate could do. Do you know any example, any paper on this subject? I am interested in mono layers structures or "sandwiched ones" such as Al/magnetic material/Al. Again thank you very much for your help.
Maybe Gd2O3, but I cannot be certain if perpendicular field can be achieved with it. Maybe in cubic phase.
Thanks a lot Aleksandar Ćirić for your answer.
Do you know any paper about this or is it just an idea? Again, many thanks.
I only know of its magnetic properties, as we produced it in our lab, nothing on the orientation.
