JOURNAL RESTRICTED ACCESSUpper critical field, Hc2(T), of PbMo6S8 was measured in a temperature region from 1.3 K to the superconducting transition temperature, Tc, using pulsed magnetic fields. Extrapolation to zero temperature indicates that Hc2(0) is about 600 kG with Tc=13.3 K.View full abstractDownload PDF (256K) -

JOURNAL RESTRICTED ACCESSNMR of 23Na and 51V in β–Na0.33V2O5 has been studied between 90 K and room temperature. The results of 23Na NMR show that sodium atoms are monovalent cations in β–Na0.33V2O5 and occupy two non-equivalent positions in equal probability. The reported anomalies of the transport and calorimetric properties were found to be originated from the first order structural phase transition by the observation of the jump of 51V nuclear quadrupole satellites of β–Na0.33V2O5 in the temperature range between 130 K and 170 K.View full abstractDownload PDF (264K) -

JOURNAL RESTRICTED ACCESSA new fct phase of disordered Fe–Pd Invar alloys was found at low temperatures. The low temperature phase diagram was obtained from X-ray diffraction experiments (4.2 K to 300 K). The fct phase ranges from 28% to 33.5% Pd at 0 K and the temperature dependence of lattice constants was determined. A decrease of the X-ray Debye temperature associated with a lattice softening was observed for 34% Pd in the low temperature region.View full abstractDownload PDF (292K) -

JOURNAL RESTRICTED ACCESSFrom the correspondence between our past cyclotron resonance work and the time resolved EHD luminescence result by Wagner-Schmid-Sauer for impurity-assisted intervalley scattering in silicon, a rather surprising conclusion is drawn that the impurities can remain “neutral” in the electron-hole liquid.View full abstractDownload PDF (284K) -

JOURNAL RESTRICTED ACCESSBrillouin scattering spectra of NaNO2 were observed in the incommensurate (antiferroelectric) phase under a precise temperature regulation. In the temperature dependence curve of the Brillouin frequency shift concerned with a longitudinal acoustic mode propagating along the [010] direction, an anomaly was found at the normal-incommensurate phase transition point. The anomaly appeared as a bend in contrast to the dip reported in the recent ultrasonic study.View full abstractDownload PDF (296K) -

JOURNAL RESTRICTED ACCESSIt is shown that the mutual interactions in the presence of impurity scattering leads to ln T term not only in the conductivity but also in the imaginary part of the self-energy function of two-dimensional electrons gas. Thus the prefactor of ln T term in the conductivity is not universal but depends on the strength of interactions.View full abstractDownload PDF (252K) -

JOURNAL RESTRICTED ACCESSIodine surface diffusion coefficient in some Ag+ ion based superionic solid films has been measured by observing the radial movement of iodine under a metallurgical microscope. The values of surface diffusion coefficient for Ag7I4PO4, NH4Ag4I5 and [(CH3)4N]2Ag13I15 are 2×10−8 cm2/sec, 6.3×10−8 cm2/sec and 7.8×10−6 cm2/sec, respectively at 25°C. The low value of iodine diffusion coefficient for Ag7I4PO4, makes it a good material for film solid state battery.View full abstractDownload PDF (292K) -

JOURNAL RESTRICTED ACCESSThe increment of the flow stress with illumination of light, Δτ, in single crystals of n-CdTe has been measured as a function of the specimen thickness, and Δτ was found to be reduced drastically below a critical thickness of ∼0.2 mm. This fact strongly suggests that the cause of the increment of flow stress is a light-induced shortening of the mean free path of multiplied dislocations, since the increment should disappear when the specimen size becomes smaller that the mean free path of the dislocations in illuminated specimens.View full abstractDownload PDF (208K) -

JOURNAL RESTRICTED ACCESSPlasmas of rare gases (Ne through Xe) were produced by a short-pulsed, high-current electron beam (600 kV, 10 kA peak, 3 ns FWHM) in a drift tube without an external magnetic field over a wider range of pressure (0.1∼30 Torr). Self-terminating laser emissions (3 ns FWHM) traveling along with the electron-beam pulse were found for 20 spectral lines (3300∼8400 Å) of singly-ionized and neutral Ne, Ar, Kr, and Xe atoms through the end window of the drift tube, and the small-signal gain coefficients were measured.View full abstractDownload PDF (272K) -

JOURNAL RESTRICTED ACCESSExperimental study of arcing is made in JFT-2 tokamak. Arcing is accompanied with the X-ray emission from a limiter. It is the most probable cause of arcing that accelerated electrons supply the large negatively biased potential to the limiter and offer the sufficient sheath potential to produce arc spot. This model well explains the monopolar arcing phenomenon in the current rising phase and in the plasma disruption phase.View full abstractDownload PDF (280K) -

JOURNAL RESTRICTED ACCESSIsentropic compression of high density metallic solid hydrogen (above 1024/cm3), which is necessary to solve the process of inertial confinement in the laser-driven compression, is investigated. The phase diagram is obtained according to Lindemann’s criterion. The pressure necessary to realize such high density and the temperature variation are estimated.View full abstractDownload PDF (252K) -
