The variation of line width (Delta H) and effective g factor (g/sub eff/) with cobalt content and with temperature is studied in a series of ferrites of composition Ni/sub 1- alpha/Co/sub alpha/Mn/sub 0.02/Fe/sub 1.9/O/sub 4+-/. Here alpha lies between 0 and 0.09; temperatures range from 20° to 340° C. A minimum in De…

Experiments and results on the interaction of tantalum with O 2 , N 2 , and H 2 are presented. The {100} is shown to be the habit plane of the segregation of the reaction products which appear to be Ta 2 O 5 , TaN , and β TaH , respectively. The role of the gas‐metal interaction on the fracture behavior of single crys…
The usual method of evaluating the harmonic components of the m.m.f. wave of a polyphase winding is to perform a Fourier analysis. This can, however, be a long and tedious process, especially for stepped waveforms, and further it is common practice to perform the analysis for two limiting current-vector positions, to…

Tavger et Zaitsev [6] ont montré que les opérations de symétrie qui ramènent le milieu cristallin sur lui-même sont en nombre plus élevé pour un cristal antiferromagnétique que pour un cristal paramagnétique. Il faut en effet considérer les « antiopérateurs » qui sont le produit d'une opération géométrique d'espace pa…

<div class="section abstract"><div class="htmlview paragraph">IT is only since World War ll that extensive study has been made of the effects of high-energy radiation on materials. However, a lack of fundamental data still prevents the making of any generalizations or detailed calculations of the effects o…
A new method is proposed for the determination of energies of activation of oxidation of metals and alloys. Metals are oxidized under conditions of linearly increasing temperature, and the activation energy may be determined from one single oxidation run. In addition the method also gives the approximate temperature r…
Vapor phase reduction of boron trichloride with hydrogen on electrically heated filaments in flow systems was investigated as a potential method for the preparation of high‐purity boron. Experiments were conducted on laboratory and bench‐scale flow reactors. Conversion efficiency was a function of mole ratio of reacta…
All single crystals of MgO which have been available contain iron-group impurities in quantities easily detectable by e.s.r. absorption. For a given impurity, the fractions in the di- and tri-valent states depend in part upon the past heat treatment and upon the concentrations of the other impurities. Energetic radiat…

Two Aerobee rockets were employed to eject relatively large amounts of sodium vapor into the earth's atmosphere. One of the flights occurred during evening twilight and sodium was placed in the sunlit atmosphere from 75 to 110 km. Sodium D-line emission (λ 5890 A) was observed in the ejected trail above 90 km, and 589…

Abstract Pressure differences between foam bubbles of unequal size are the cause of gas transfer from small to larger bubbles. The rate at which the small bubbles decrease in size is calculated as a function of the radius of the bubbles, the surface tension of the liquid and the thickness and permeability of the liqui…
