Abstract

The elastic electron scattering by a nonuniform magnetic field of remote nanomagnets in graphene is considered with the help of a modified Born approximation. The nanomagnets are modeled by point-like magnetic dipoles oriented transversally and in parallel to the graphene plane. They can form rather high magnetic fields without any damage of the graphene plane. The electron scattering cross sections are obtained in the closed form and analyzed numerically. It is shown that this mechanism of scattering has nonzero backscattering cross-section and can considerably affect the graphene conductivity.
