"Organic materials offer unique properties like: i) processablility and plastic technology compatibility, ii) monodispersity and tunability and iii) long time spin coherence that make them appealing for spintronics devices and hence, a great number of proposals exits about its use in spintronics applications. Nevertheless, organic spintronics is in its infancy and so far only a small number of different organic materials have been used in spintronic research to realize an even smaller number of this proposals. First reports on the integration of organic materials into spintronic devices date back to 2002. Self-assembled monolayers with their special characteristics are an invaluable tool set for the developing and understanding of spin transport. As tunnel barriers SAMs i) Can be easily engineered: Are modular and their parts can be exchanged while keeping the others unchanged, ii) Are intrinsically nanometre thick: Film thickness will be determined by molecule size and SAM structure, iii) Have defined structures: SAM formation is a self-assembly process, structure is preprogramed and iv) Are promising to candidates to work at high-bias. SAMSFERE aims to expand the current know-how in the field of organic spintronics and lay the base of a solid understanding of the spin-transport through interfaces by the growing of a completely new set of SAMs over FM electrodes that will be employed in the development of devices based on magnetoresistive effects(organic magnetic tunnel juntions) and beyond (spin organic light-emmiting diodes)."
