▎ 摘　　要

We study the energy spectrum and electronic properties of graphene in a periodic magnetic field of zero average with a symmetry of triangular lattice. The periodic field leads to the formation of a set of minibands separated by gaps, which can be manipulated by an external field. The Berry phase, related to the motion of electrons in k space, and the corresponding Chern numbers characterizing the topology of the energy bands are calculated analytically and numerically. In this connection, we discuss the anomalous Hall effect in the insulating state, when the Fermi level is located in the minigap. The results of calculations show that in the model of a gapless Dirac spectrum of graphene, the anomalous Hall effect can be treated as a sum of fractional quantum numbers, related to the nonequivalent Dirac points.
