The paramagnetic resonance absorption spectra of ${\mathrm{Tb}}^{+++}$ ions in single crystals of CaW${\mathrm{O}}_{4}$ and Ca${\mathrm{F}}_{2}$ have been studied at 4.2\ifmmode^\circ\else\textdegree\fi{}K over a wide range of frequencies from 4 to 50 kMc/sec. The observed spectra fit a simple spin Hamiltonian $\mathc…

The problem of electron binding in solutions is treated on the basis of a continuum model. The polarizable medium is represented by a continuum, which can be characterized by macroscopic properties, e.g. the static and the optical dielectric constants. The motion of an additive electron is determined by its interactio…

Abstract A previously-reported theory for the Mullins softening effect has been used to interpret various new data for the behavior of filled SBR, rubber under tensile load. The strength of the filler-rubber bond, the filler surface area per polymer molecule attachment, and the average filler surface separation have b…
Eight low-lying levels of Er ii 4f12 6s have been observed to be grouped according to their energy in four close pairs. The centers of gravity of the pairs correspond to the energies of the four lowest levels of the core 4f12; the spacings between the two components of the pairs depend on the Coulomb interaction betwe…
The rapid evaporation or condensation of a vapor bubble when out of equilibrium compared to the slow dissolving or growth of an air bubble results in quite different propagation properties of sound waves through water containing one or the other types of bubbles. Adapting a method developed by Foldy in his treatment o…
Four types of measurement on thin Permalloy films are discussed which in the coherent-rotation theory yield equivalent values for the anisotropy field Hk: (A) Hysteresis loop; (B) high field torque; (C) rotational hysteresis; (D) torque 90° to the easy axis. Results reported for several films show that the values obta…
Some ferroelectric and crystallographical properties of the compound ${\mathrm{Bi}}_{4}$${\mathrm{Ti}}_{3}$${\mathrm{O}}_{12}$ are presented.

Tetrahedrally-coordinated trivalent iron has been found to be a common impurity in flux-grown crystals of zinc oxide. The room temperature paramagnetic resonance spectrum of isolated ions may be described by a conventional axial spin Hamiltonian with parameters: $g=2.0060\ifmmode\pm\else\textpm\fi{}0.0005$, $D=\ensure…
The structure of the interrnetallio compound Co4Al,a is similar to that of 'FeA1 a' with which it forms a complete series of solid solutio~m. Refinement of the structure reveals certain differences in detail.
Changes in the structure of PTFE produced by different cooling rates from the sintering temperature and following permanent mechanical deformation have been studied with the electron microscope. Slow cooling rates resulted in longer and wider striated bands (which constitute the PTFE) than fast cooling rates, however,…

The effect of adding the rare-earth elements to cobalt, iron, and nickel has been investigated. Antiferromagnetic coupling was found to exist in the cobalt and iron rare-earth compounds. The moment per formula unit of the compound Co5Y is increased when Sm, Pr, and Nd are substituted for yttrium and decreased when Tm,…

The locus of points on the (α,κ/σT) plane for a two-band (electrons and holes) semiconductor as the concentration of doping agent is changed, is a curve that forms a closed loop, where α is the Seebeck coefficient, κ the thermal conductivity, σ the electrical conductivity, and T the absolute temperature. The value of…
