10 p, 5.1 MB Graphene spintronics : puzzling controversies and challenges for spin manipulation / Roche, Stephan (Institut Català de Nanociència i Nanotecnologia) ; Valenzuela, Sergio O. (Institut Català de Nanociència i Nanotecnologia)
This article presents the current puzzling controversy between theory and experimental results concerning the mechanisms leading to spin relaxation in graphene-based materials. On the experimental side, it is surprising that regardless of the quality of the graphene monolayer, which is characterized by the carrier mobility, the typical Hanle precession measurements yield spin diffusion times in the order of which is several orders of magnitude below the theoretical estimates based on the expected low intrinsic spin-orbit coupling in graphene.

The suitability of a particular material for use in magnetic devices is determined by the process of magnetization reversal/relaxation, which in turn depends on the magnetic anisotropy. Therefore, designing new ways to control magnetic anisotropy in technologically important materials is highly desirable. [...]
