  We study interlayer transport of multilayer graphenes in magnetic field with
various stacking structures (AB, ABC, and AA types) by calculating the Hall and
longitudinal conductivities as functions of Fermi energy. Their behavior
depends strongly on the stacking structures and selection of the layers. The
Hall conductivity between different layers is no longer quantized. Moreover,
for AB stacking, the interlayer conductivity vanishes around zero energy with
increasing layer separation, and shows negative values in particular cases. The
fact that longitudinal interlayer conductivity suppressed by the magnetic field
indicates that this system can be applied as a switching device.
