Variable Range Hopping Conduction

Electrical resistivities of double perovskite oxides Sr 2 Fe ( W 1-x Mo x) O 6 have been measured at high pressure and high magnetic field to elucidate the transport properties of these materials. It is found that the main mechanism of the transport in the semiconducting phase is variable range hopping conduction and the insulating properties are suppressed by high pressure to show a crossover to metallic state. The magnetoresistances of these oxides are revealed to decrease at high pressure above 1 GPa. Extremely large Grüneisen parameters are found near x = 0.2, where the metal-insulator transition occurs. The origin for these properties will be briefly discussed in connection with the phase diagram.

ABSTRACT1, 4-Bis [2-(tetrathiafulvalen-2-yl)ethenyl] -2, 5-dimethylbenzene (BTFE-DMB) is synthesized and its structure is found to be planar. The single crystal of its iodine salts undergoes a metal-insulator transition about 180K. The compaction pellets of the iodine salts show the current dependent resistive anomaly under high pressure.
