ABSTRACT
After the discovery of single-layer graphene, the science of
graphene has quickly become widespread in the world. Research
on technological applications of graphene to various devices is
also in progress throughout the world. The discovery of new
phenomena and novel materials could contribute to human society;
however, many difficulties should be overcome before achieving
this purpose. A successful example of such activities may be the
research in spintronics developed after the discovery of giant
magnetoresistance (GMR) in magnetic multilayers. Spintronics is a
field of science and technology that utilizes both charge and spin
degrees of freedom of electrons discovered about 100 years ago
[1, 2]. Graphene could be applied to devices in the field of spintronics
and also to novel ones by using characteristic features of graphene
outside the field of conventional spintronics. To develop such a new
field, comparison of the research in the field of graphenewith that in
spintronics might be effective. In this chapter we give an overview of
the research on graphene and in spintronics. The overview, however,
could not be comprehensive but is restricted within limited subjects
because the research activities of graphene are so vast in the
world.
