AbstractWe observed a dramatic peak in the 1/f noise at the metal-insulator transition (MIT) in low-Tc, manganites. This many-orders-of-magnitude noise enhancement is observed for both polycrystalline and single-crystal samples of La5/8−y. Pry, Ca3/8MnO3 (y = 0.35 – 0.4) and Pr1−xCaxMnO3 (x = 0.35 – 0.5). This observation strongly suggests that the microscopic phase separation in the low-Tc, manganites causes formation of a percolation network, and that the observed MIT is a percolation threshold. It is shown that the scale of phase separation in polycrystalline samples is much smaller than that in single crystals.

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.

Ultrathin Sm0.6Nd0.4NiO3−δepitaxial films were deposited by pulsed laser deposition (PLD) onto LaAlO3(LAO) single crystal substrates. TheTMIof the SNNO films remarkably decreases with the decrease of the growth oxygen pressure, while the strain state varied slightly.
