概要 The interlayer magnetoresistance in a multilayered massless Dirac fermion system, α(BEDT-TTF)2I3, under hydrostatic pressure was investigated. We succeeded in detecting the zero-mode n=0 Landau level and its spin splitting in the magnetic field normal to the two-dimensional plane. We demonstrated that the effective Coulomb interaction in the magnetic field intensifies the spin splitting of zero-mode Landau carriers. At temperatures below 2 K, magnetic fields above several Tesla break the twofold valley degeneracy.
