Research summary

My research is focused on a new area of technology called spintronics, which is a branch of electronics that is aimed at exploiting the property of the spin of the electron in addition to its charge. My project is targeted at developing a new class of materials based on nanoscale functional units such as molecule magnets and magnetic nanoparticles that can detect or create magnetic fields, and record and store information. The key challenge is the coupling of these nanoscale units to the macroscopic world, which is essential for read and write purposes. One- dimensional carbon nanostructures such as carbon nanotubes and nanofibers with one macroscopic and two nanoscopic dimensions provide an excellent means to achieve this coupling. The main advantage of my approach is that for the first time scientist will be able to exploit the excellent electrical and spin transport properties of the host-nanocontainers, while tailoring the one- dimensional organisation of these nanomagnets with nanoscale accuracy. The confinement within the host-nanocontainers that act as protective shields offers the opportunity to control the assembly and magnetic properties of the guest nano -sized magnets. In turn, the guest-species can influence the electrical resistance of the host nanotubes as the direction of the magnetic field change.

?The findings of my research will contribute to overcome the current challenges to develop spintronic devices that will increase computing performance with lower power consumption, functionality and communication speed far beyond the expected limits of the conventional technology. Advances in this area will affect the global economy specially the microelectronic business, the environment and the society in general making people ´s lives easier. The materials obtained here will have an impact not only on information, communication and nanoelectronics technologies but also in catalysis due to spatial confinement effects.
