Elastic Constants and Soft Optical Modes in Gadolinium Molybdate
The complete set of elastic constants in single-crystal gadolinium molybdate (GMO) is presented in a temperature range from 20 to 200 \ifmmode^\circ\else\textdegree\fi{}C. This covers the structural phase transition at 159 \ifmmode^\circ\else\textdegree\fi{}C, below which GMO is both ferroelastic and ferroelectric. El…
Thermal stability of thin PtSi films on silicon substrates
The thermal stability of PtSi is an important parameter in large-scale integration processing schemes which involve postmetallization high-temperature operations. For this reason, the effect of annealing on various properties of PtSi has been studied over the temperature range 800–900°C, for 200- and 900-Å-thick PtSi…
Effect of Proton-Phonon Coupling on the Ferroelectric Mode in KH2PO4
The low-frequency Raman spectra of crystal K${\mathrm{H}}_{2}$P${\mathrm{O}}_{4}$ are reexamined experimentally. For temperatures above the Curie point, the ${B}_{2}$ spectra below 270 ${\mathrm{cm}}^{\ensuremath{-}1}$ are fitted to the model of two coupled harmonic oscillators. When the proton-phonon-coupling effect…
The plasma polymerization of vinyl monomers. II. A detailed study of the plasma polymerization of styrene
Abstract A study has been made on the plasma polymerization of styrene monomer in a cold, low‐power, inductively coupled RF plasma. Styrene monomer yielded an insoluble, crosslinked film which was slightly colored. A kinetic study is reported for styrene. The effects of power level, bleed rate of monomer, pressure, an…
Angular Distribution of Electrons Elastically Scattered fromN2
The angular distribution of electrons elastically scattered from ${\mathrm{N}}_{2}$ as a function of energy has been measured utilizing a crossed-beam technique. Measurements have been made of monoenergetic electrons with energies between 5 and 90 eV scattered from a collimated beam of ${\mathrm{N}}_{2}$ at angles fro…

Neutron-Scattering Study of the Ferroelectric Phase Transformation inTb2(MoO4)3
We establish a first example of a ferroelectric phase transformation where a Brillouin-zone-boundary soft mode [at the $M$ point (\textonehalf{}\textonehalf{},0)] rather than a Brillouin-zone-center mode of the parent paraelectric phase (PE) is responsible for the transition. By inelastic scattering of neutrons, we ha…

The Observation of Incipient Phase Transitions in K2PtCl6, K2PdCl6, and K2IrCl6
Measurements of the temperature dependence of the nuclear quadrupole resonance (NQR) frequencies and spin–lattice relaxation times for the 35 Cl nuclei in Cs 2 PtCl 6 , Rb 2 PtCl 6 , K 2 PtCl 6 , and K 2 PdCl 6 provide information on the temperature dependence of two averages of the rotary lattice mode frequency over…
Die Kristallstruktur von Ba13Al22Si10O66
Single crystals of Ba 13 Al 22 Si 10 O 66 were investigated by x-ray methods. The compound crystallizes in the hexagonal space group P 6 3 , with the unit-cell dimensions a = 9.955 ± 0.001 Å, c = 18.590 ± 0.005 Å. There is one formula unit in the unit cell. Three-dimensional Patterson and Fourier syntheses have been c…
Electrical conductivity of heavily doped diamond
The semiconducting properties of boron-, aluminum-, and titanium-doped diamond have been interpreted using the log R (resistance) vs 1/T curves. In boron-doped diamond, ``high-concentration''-type impurity band conduction occurs. The extrinsic ranges of the curves are analyzed with the usual model to yield the activat…
Magnon Heat Conduction and Magnon Scattering Processes in Fe-Ni Alloys
The thermal and electrical conductivities of 70-wt%-Ni-30-wt%-Fe, 81-wt%-Ni-19-wt%-Fe, and 67-wt%-Ni-33-wt%-Cu have been measured between 1.5 and 4.5 K, in external fields up to 6 T. Both nickel-iron alloys show a small magnon contribution ${\ensuremath{\kappa}}_{m}$ to the thermal conduction, equal to about 3% of the…

Fe-Cr-Co permanent magnet alloys containing silicon
The magnetic properties of Fe-Cr-Co alloys as a function of the additional silicon content was studied. It was found that the magnetic properties depend on the compositions of the alloys and the best properties were obtained with an alloy of Fe-28wt%Cr-23wt%Co-1wt%Si. The energy product of this alloy attains 5.3 MGOe…
Expansion and Contraction of Planar, Cylindrical, and Spherical Underwater Gas Bubbles
The one-dimensional motion of a planar gas bubble, the axially symmetric motion of a cylindrical bubble, and the spherically symmetric motion of a spherical bubble in a liquid are considered. Following J. B. Keller and I. I. Kolodner [J. Appl. Phys. 27, 1152–1161 (1956)], the velocity potential in the liquid is assume…

Measurement of Fracture Surface Energy of SiC
The fracture surface energies of 5 polycrystalline silicon carbides were measured at room temperature using the double‐cantilever‐beam, notched‐beam, and work‐of‐fracture methods. All methods yielded comparable fracture surface energies,
Effect of Oxide Defect Structure on the Electrical Properties of ZrO 2
The defect structure of monoclinic ZrO 2 was studied by measuring the transfer numbers and electrical conductivity as functions of O 2 pressure and temperature. The data suggest a defect structure of doubly ionized oxygen vacancies at low pressures, i.e. <10 −19 atm, and singly ionized oxygen interstitials at press…
