Graphene is one of the most popular new materials both in the academic and private sectors. Its striking properties allow for radical redesigns of many electronic or storage devices. In this report, first, a brief theoretical description of graphene’s band structure is given using the tight/binding method, along with its unique properties. The principal objective is to explore how such electrical properties lead to spintronics applications. In graphene, due to low spin-orbit coupling, exceptional spin transport is observable. Hence, a practical introduction to some electrical and magnetic measurements on spin-valve devices is followed by some experimental results. In addition, key electrical properties of graphene such as sheet resistance, mobility, and Dirac point are calculated.
