Abstract
We report on the experimental results of interlayer magnetoresistance in the multilayer massless Dirac fermion system under hydrostatic pressure and its interpretation. We succeeded in detecting the zero-mode Landau level ( Landau level) that is expected to appear at the contact points of Dirac cones in the magnetic field normal to the two-dimensional plane. The characteristic feature of zero-mode Landau carriers including the Zeeman effect is clearly seen in the interlayer magnetoresistance.
