Abstract

We have investigated the impact of Ru substitution on the multi-band electronic structure of FeSe$_{1-x}$Te$_x$ by means of angle-resolved photoemission spectroscopy (ARPES). The ARPES results exhibit suppression of the $xy$ Fermi surface and the spectral broadening near the zone boundaries, which can be associated with the lattice disorder introduced by the Ru substitution. The degeneracy of the Fe 3$d$ $yz$/$zx$ bands at the zone center, which is broken in FeSe$_{1-x}$Te$_x$, is partly recovered with the Ru substitution, indicating coexistence of nematic and non-nematic electronic states., Comment: 5 pages, 4 figures

29. Interplay between magnetism and conductivity in the one-dimensional organic conductor TPP[Fe(Pc)(CN)2]2

Author

Kimata, M., Takahide, Y., Harada, A., Satsukawa, H., Hazama, K., Terashima, T., Uji, S., 1000020227713, Naito, T., Inabe, T., Kimata, M., Takahide, Y., Harada, A., Satsukawa, H., Hazama, K., Terashima, T., Uji, S., 1000020227713, Naito, T., and Inabe, T.

Abstract

The strongly nonlinear current-voltage (I-V) characteristics and the large negative magnetoresistance (MR) are observed at low temperatures in the one-dimensional organic conductor TPP[Fe(Pc)(CN)2]2. The nonlinear I-V curves are interpreted as the transport of the electrons and holes excited from the charge ordered state on the Fe(Pc)(CN)2 chains, whose energy gap strongly depends on electric fields. The negative MR is enhanced as temperature decreases, and the resistance steeply changes over four orders of magnitude around 15 T at 1.5 K. This decrease is associated with a magnetic torque anomaly, and the energy gap is rapidly reduced around 15 T. The detailed analyses of the I-V curves show that the electric flux distribution, i.e., the dimensionality of the Coulomb interaction between the carriers, also changes around 15 T.

Abstract

Thermal analysis of Ag(DM)2, where DM = 2,5-dimethyl-N,N’- dicyanoquinonediimine, clarified that the salt had an insulating amorphous phase ( ≥ 155°C). Characterization of this and related solid states of Ag(DM)2 indicated that a photo-induced process should be essential in controlling the number of carriers and thus conduction behavior of the salt by illumination. In fact, while heating could do nothing but make the salt insulating when the sample temperature exceeded 155°C, ultraviolet-visible light illumination ( < 155°C) could gradually change the properties to be semiconducting with retaining the crystal lattice (average structure).

44. Carrier dynamics in an organic magnetic superconductor and related salts κ, λ-(BETS)2MCl4 (M = Fe, Ga)

Author

Naito, T., Matsuo, S., Inabe, T., and Toda, Y.

Abstract

In order to compare the carrier dynamics and reveal the origin of differences in their electrical behaviour, time-resolved reflectivity changes were measured on single crystals of the title compounds. The observed relaxation behaviour well explained their electrical behaviour, and indicated that different conduction mechanisms dominated κ-and λ-type BETS salts, irrespective of local spins, at ca. 8-100 K; the electrical behaviour of the κ-type salts is governed by relaxation times of carriers and/or density of states at the Fermi levels, while that of the λ-type salts is dominated by the latter.
