Abstract Dynamic mechanical properties of polystyrene (PS) and polymethylmethacrylate (PMMA) filled with glass beads and mica flakes have been investigated. The α‐dispersion temperature ( T α ) increases with filler content in each system. The increase in T α is larger for PMMA than for PS in the case of the same fill…

Various means of deuteration have been used to establish the hydrogenic origin of both the 119-G and 74-G hyperfine doublets observed in a variety of irradiated vitreous silica samples. The g values of both these defects appear inconsistent with an earlier model in which these lines were attributed to a hole localized…

The problem of the highly correlated electron gas ${\mathrm{V}}_{2}$${\mathrm{O}}_{3}$ consisting of a filled ${a}_{1g}$ and a quarterly full ${e}_{g}$ band is treated on the basis of a Hartree-Fock calculation with spin and orbit unrestriction. The values of the effective hopping integrals which include covalency eff…

We find that certain cyano Schiff bases and cyanobiphenyls with alkyl or alkoxy end groups exhibiting a bilayer smectic-$A$ phase, also exhibit a reentrant nematic phase at high pressure. A tentative model of the bilayer smectic-$A$ phase and the mechanism whereby the reentrant transition may occur is presented.

For pt.I see Act Crystallogr., vol.B32, p.1348 (1976). The intermetallic compound Fe 3 Sn 2 has been studied by neutron diffraction and magnetisation measurements. This compound is ferromagnetic (T C =657K). At room temperature the spin direction is along the c axis. A spin rotation is observed between approximately 2…

Research on metal–insulator transitions is at the moment quite fashionable. In many materials the electrical behavior changes from metallic to nonmetallic when the pressure, temperature or magnetic field is varied or (as in alloys) when the composition is varied, and the theoretical description of these processes is q…

The structure parameters of Li 3 N in the temperature range -120 to 20°C were refined both for neutral atoms (Li 0 and N 0 ) and for ions (Li + and N 3- ). For N 3- new scattering curves were used which were calculated by applying stabilizing Watson-sphere potentials for different radii. All structure parameters depen…

The variation of electrical resistivity of an insulator-conductor composite, namely, wax-graphite composite, with parameters such as volume fraction, grain size, and temperature has been studied. A model is proposed to explain the observed variations, which assumes that the texture of the composite consists of insulat…

The elastic and misfit strain in vapor-grown InGaP/GaAs crystals was determined by measuring the lattice parameter of the InGaP before and after removal of the GaAs substrate. The energy-band-gap shift as a function of strain was measured in a similar manner using photoluminescence. Up to 70% of the misfit strain was…
