  This article reviews recent results of magnetotransport and magnetization
measurements performed on highly oriented pyrolitic graphite (HOPG) and single
crystalline Kish graphite samples. Both metal-insulator and insulator-metal
transitions driven by magnetic field applied perpendicular to the basal planes
of graphite were found and discussed in the light of relevant theories. The
results provide evidence for the existence of localized superconducting domains
in HOPG even at room temperature, as well as an interplay between
superconducting and ferromagnetic correlations. We also present experimental
evidence for the superconductivity occurrence in graphite-sulfur composites.
