Electric resistivity and  magnetoresistance of some superhard and ultrahard fullerites in the range 300-2K

• Electric resistivity and magnetoresistance were measured on samples with disordered structure synthesized from pure C60 and C70 at pressures in the range 8 - 12.5 GPa and temperature 900 - 1500 K. Different type of behaviour were observed: semimetallic and semiconducting, depending on the particular short-range order of the structure.
