中文摘要	The authors have investigated resonant tunneling in nonuniform magnetically modulated graphene-based double-barrier structures, which can be realized experimentally by depositing successive ferromagnetic stripes on graphene monolayer. The effects of Klein tunneling, resonant tunneling, and magnetically induced wave vector filtering on the shot noise are taken into consideration. It is found that the shot noise is enormously enhanced in antiparallel magnetization alignment, and striking Poissonian value plateaus of the Fano factor can be formed, which is dramatically distinguishable from that in parallel alignment. The results indicate that the shot noise could be a sensitive probe to reveal mechanism of electronic transport in graphene.
