Description
Molecular spintronics deals with the study of utilising the internal spin degree of metal-organic frameworks, at low temperatures, to develop next generation of nanoscale devices. However, research effort in the last few years has shown the possibility to develop induced spin-systems by tailoring the interface chemistry between a transition metal surface and an otherwise diamagnetic or paramagnetic molecule. Reports of induced magnetism in molecule or transition metal surface, magneto-resistance signals, large magnetic anisotropy and magnetic exchange coupling across the interface have emerged, with the effects lasting up to room temperature. These findings open up a molecular-genome initiative to develop spin-functional tailor-made devices by engineering the interface spin-response.
