Molecular Spintronics
Molecular spintronics is recognized to as an attractive new research direction in a field of spintronics, following to metallic spintronics and inorganic semiconductor spintronics, and attracts many people in recent decades. The purpose of this manuscript is to describe the history of molecular spintronics by introducing important achievements and to show the current status of this field. In addition, the authors briefly introduce several theories for implementing studies in molecular spintronics.
