Magnetic field nanosensor based on Mn impurities
Journal Title: INCAS BULLETIN - Year 2014, Vol 6, Issue 2
Abstract
Nanosensors based on graphene nanoribbon, studied in the present work, could provide a special interest in (aero) space applications. More specifically, the paper proposes the construction of a nanosensor based on Mn (Manganese) impurities. Different spin configurations of the Mn atoms are considered. The mathematical model used to determine the spin transport is based on Kohn-Sham equations. The spin-dependent transmission functions are calculated using the formalism of the nonequilibrium Green’s functions. The implementation of the mathematical model is performed in the SIESTA package. The spin transport properties are determined using the first principle calculations using density functional theory. The graphene nanoribbon with transition metal impurities is based on active element – the system of spins – which is influenced by the external perturbation field. Such nanostructures may serve as spatial applications. The differences between different excited states are determined and it is established that the energy range overlaps the mid-infrared wavelengths.
