ABSTRACT
Spin transport electronics or spintronics is the study of the electron spin and associated magnetic field in addition to its charge in quantum transport in solid state devices. The experimental discoveries related to spin-dependent electron transport in solid state physics in the 1970s and 1980s led to the emergence of the concept of spintronics. The first experiments in the 1970s on spintronics were done by Meservey and Tedrow using ferromagnetic/superconducting junctions and by Julliere using magnetic tunnel junctions. Spin-polarized current can be generated in a metal by passing current through a ferromagnetic material. Giant magnetoresistance is one such example. Spintronics applied to organic chemistry has developed into a potentially promising field with rich physics and new applications such as organic spin valves, bipolar spin-valves, and hybrid organic/inorganic light emitting diodes. Coherent control of the ferromagnet-organic interface is one of the major issues of organic spintronics. Conventional micro-fabrication techniques cannot be used because of the extremely fragile nature of organic materials.
