There are strong reasons from dc and pulsed-current measurements, and from thermal conductivity results, for thinking that narrow channels through
This paper reports ballistic magnetoresistance values over 4000% measured in electrodeposited Ni-Ni nanocontacts with T geometry previously developed . Over
We theoretically estimate the electron-phonon coupling constant lambda for metallic single-walled carbon nanotubes with a diameter of 1.4 nm. The
A ferromagnetic semiconductor, rutile (Ti,Co)O2, exhibits anomalous Hall effect at room temperature. Strong dependence of the anomalous Hall effect, as
We show that the off-shell contributions in Compton scattering by pion may exist only in the single exchange diagrams. These
Searle's Chinese Room argument is refuted by showing that he has actually given two different versions of the room, which
While microscopic laws of physics are invariant under the reversal of the arrow of time, the transport of energy and
We report the bulk sensitive Hard X-ray (hv=5.95keV) core level photoemission spectroscopy to investigate the intrinsic electronic structure of strained
Magnetotransport properties in a nanocrystalline La$_{0.67}$Sr$_{0.33}$MnO$_{3}$/micron sized Al$_{2}$O$_{3}$ granular composite with different concentrations of Al$_{2}$O$_{3}$ have been studied. The resistivity
We have studied Bi-2212 microcrystals aged at ambient conditions for 40 days. Combined x-ray absorption near edge structure and x-ray
Modern PC workstations often provide more CPU power than required for most control applications. On the other hand, the screen
The search for macroscopic magnetic ordering phenomena in organic materials, in particular in pure graphite, has been one of the
In the vicinity of their resonance frequency, piezoelectric resonators are highly sensitive to small perturbations. The present report is focussed
The giant transverse magnetoresistance is observed in the case of photoinduced nonequilibrium carriers in an asymmetric undoped system of three
The ferromagnetic phase in La0.7Sr0.3MnO3 manganite is completely spin polarized (100%) at room temperature. This is demonstrated on high quality
A simple model is used to analyse published results on large room-temperature diamagnetism for two films of oxidised atactic polypropylene
It is well known that copper-based perovskite oxides rightly enjoy consensus as high-temperature superconductors on the basis of two signatures:
Is there any room for new physics in the muon g-2 problem?
Guided by the internal-reference rule and the known band offsets in III-V and II-VI diluted magnetic semiconductors, we discuss the
We present measurements of electrical resistivity, thermal conductivity and thermopower of polycrystalline Sr-doped LaCoO3 with composition La0.95Sr0.05CoO3. Our data show
We review recent advances in the physics of strongly interacting charged systems functioning in water at room temperature. We concentrate
We report on far infrared measurements on Zn and Si doped crystals of the spin-Peierls compound CuGeO3. Zn doping has
Some references for the breaking strength of fused silica fibers compiled in 1999.
Multiwalled carbon nanotubes are shown to be ballistic conductors at room temperature, with mean free paths of the order of
