Electronic excitations and electron-phonon coupling in bulk graphite through Raman scattering in high magnetic fields

We use polarized magneto-Raman scattering to study purely electronic excitations and the electron-phonon coupling in bulk graphite. At a temperature of 4.2 K and in magnetic fields up to 28 T we observe K-point electronic excitations involving Landau bands with Delta vertical bar n vertical bar = 0 and with Delta vertical bar n vertical bar = +/- 2 that can be selected by controlling the angular momentum of the excitation laser and of the scattered light. The magnetophonon effect involving the E-2g optical phonon and K-point inter-Landau-band electronic excitations with Delta vertical bar n vertical bar = +/- 1 is revealed and analyzed within a model taking into account the full k(z) dispersion. These polarization-resolved results are explained in the frame of the Slonczewski-Weiss-McClure model which directly allows the quantification of the electron-hole
