• Molecular Spintronics
    is a new field of research that combines the ideas and concepts developed in spintronics with the possibilities offered by molecules to perform
    electronic functions, to form self-organized nanostructures and to exhibit quantum effects.

    It ultimate goal is the creation of new spintronic devices using molecular materials, or in the longer term one or a few molecules in the race
    toward miniaturization.
  • To reach this goal a coordinated effort of the communities of Spintronics, Molecular Electronics and Molecular Magnetism is needed.

    These communities are developing a very competitive and high-quality work in Europe in their respective fields. Still, Molecular Spintronics is so
    new that an initiative to encourage networking of researchers in this field is of paramount importance.

    The present COST ACTION intends to fill this gap integrating these communities around a common Action that should serve to consolidate the
    world-leadership of Europe in this field.
As pointed out before, only the initial steps in organic spintronics have been undertaken. To reach the final goal in this sub-area (i.e., to design cheaper spintronic devices compatible with plastic technology), a long way needs to be pursued that involves a strong coordinative effort of the spintronics community with the two molecular communities in three major topics: i) The engineering of interfaces that allow tuning of the spin injection from the ferromagnetic electrode to the molecular spin collecting layer; ii) A better understanding of spin-dependent transport phenomena through molecular systems; iii) The design of new types of spintronic devices taking advantage of the multifunctional properties of molecular systems.

As far as the single-molecule nanospintronics is concerned, the progress beyond the state-of-the-art will take advantage of the possibility to tailor and manipulate molecules down to the single spin. Currently, this sub-area is strongly hindered by the reproducibility of the devices and by the chemical unstability of the magnetic molecules when they are in contact with the metallic electrodes. Still, the advances made in organic spintronics in relation with the hybrid interfaces formed by molecules organized on inorganic surfaces can serve as starting point to improve the stability of these nanodevices and to study the properties of these molecules individually. On the other hand, the addressing and readout of a single spin in these devices is another challenge that has been proposed theoretically but that needs to be demonstrated experimentally. In particular, scale reduction of the spintronic device down to a single molecule remains an open challenge. Finally, the use of magnetic molecules as spin qubits should allow for the development of quantum devices based on these units. However, this is a long term challenge. In the short term, the next steps will focus on increasing the coherence times of these molecules and integrating these qubits in scalable architectures by exploiting the ability of molecules to self-assemble.
