| Research Abstract |
We have discovered first bulk massless Dirac fermion systems in an organic conductor α-(BEDT-TTF)_2I_3under high pressure. One of the characteristic feature is that the zero-mode Landau level always exist at the zero-energy in magnetic field. In this work, we succeeded in detecting the effects of zero-mode including its spin splitting on inter-layer transport. The most impressive findings are that the multi-band Dirac fermion systems with both Dirac particles and normal electrons are realized in Θ-(BEDT-TTF)_2I_3.
