Controlling the interactions at the interface of a magnetic/topological insulator heterostructure is an outstanding challenge with implications in fundamental science and technology. An international team of researchers (Spain, Switzerland, Italy) has shown that it is possible to tune the interfacial interaction without quenching the molecular spin and the topological surface state of the topological insulator by choosing suitable organic ligands. They found that CoTBrPP and CoPc monolayers (metal-organic molecules) adsorbed on Bi2Te3 (topological insulator) form robust interfaces where electronic interactions can be tuned without strongly perturbing the intrinsic properties of each constituent. Their conclusions are supported by structural, electronic, and magnetic information derived from a combination of specialized techniques. The emergence of dissipationless spin currents can be exploited in novel spintronic devices, metrology or in electron-spin based quantum information applications…read more.
