چکیده
The magnetic, transport, optical, and structural properties of quasi-one-dimensional BaIrO3 show evidence for the simultaneous onset of electronic density wave formation and ferromagnetism at Tc3 175 K: Two additional features in the chain direction dc conductivity show a sudden change to metallic behavior below Tc2 80 K and then a Mott-like transition at Tc1 26 K: Highly non-linear dc conductivity, optical gap formation at <9kBTc3, additional phonon modes, and emergent X-ray satellite structure support density wave formation. Even at very high (30 T) fields the saturation Ir moment is very small, <0.04mB/Ir. q 2000 Elsevier Science Ltd. All rights reserved.

A general theoretical approach to double photoemission from solid surfaces is formulated in terms of two-electron Green functions and two-electron states. By incorporating the screened Coulomb interaction between the two outgoing electrons in a dynamically screened effective one-electron potential, approximate expressions for the two-photoelectron current are derived, which essentially consist ...

We have produced phototransformed C60 in powder form and in bulk quantities. The availability of several milligram batches allowed us to collect good quality X-ray powder diffractograms, infrared transmission spectra and differential scanning thermograms. Based on these data a disordered structural model is proposed which is built up from small closed oligomers. q 1999 Elsevier Science Ltd. All...

We have studied the effect of the magnetic field on the indirect excitons in coupled quantum wells in GaAs at magnetic fields up to 25 T. An unexpectedly large red shift of the indirect exciton line occurs at relatively low magnetic field. This shift depends strongly on the electric field applied parallel to the growth direction. q 2000 Elsevier Science Ltd. All rights reserved.

Eigenstates of two-dimensional charged electron–hole complexes in magnetic fields are considered. The operator formalism that allows one to partially separate the center-of-mass motion from internal degrees of freedom is presented. The scheme using magnetic translations is developed for calculating in strong magnetic fields the eigenspectra of negatively charged excitons X, a bound state of two...

The temperature dependence of the Raman-active mode frequencies in indium sulfide was measured in the range from 10 to 300 K. The analysis of the temperature dependence of the Ag intralayer optical modes show that Raman frequency shift results from the change of harmonic frequency with volume expansion and anharmonic coupling to phonons of other branches. The pure-temperature contribution (phon...
