| Research Abstract |
We have measured the specific heat of the organic conductor α-(BEDT-TTF)_2I_3 under pressure where the massless Dirac fermion system with linear energy dispersion is realized. In low temperature, the specific heat shows almost ∝T^2 dependence, and shows the peak and saturation in magnetic field. These behaviors are well understood by assuming the linear dispersion and N=0 Landau level characteristic of the Dirac fermion system. The results are also quite consistent with the reported magnetoresistance.
