The ionic conductivity of Li‐halide crystals

Y. Haven1950-01-01Recueil des Travaux Chimiques des Pays-Bas

Abstract The ionic conductivity of mixed crystals of Li halides and Mg halides has been measured. From these measurements the mobility of Li vacancies and the concentration of vacancies in pure Li halides has been derived, with the two assumptions that the defects in Li halides are Schottky defects and the mobility of…

Wide-Angle Metal-Plate Optics

J. Ruze1950-01-01Proceedings of the IRE

The design equations for constrained metal-plate lenses are derived. These lenses prove to have exceptional wide-angle scanning properties. The scanning aberrations are investigated by means of a power series expansion of the phase error. This analysis indicates that the square-law error is a function of lens depth an…

Dimensional Effects Resulting from a High Dielectric Constant Found in a Ferromagnetic Ferrite

Frank G. Brockman、P. H. Dowling、Walter G. Steneck1950-01-01Physical Review

A variety of a ferromagnetic ferrite is shown to have dielectric properties corresponding to a dielectric constant of the order of ${10}^{5}$. Coupled with a magnetic permeability of about ${10}^{3}$, this leads to dimensional resonance effects such that the apparent permeability of a core whose section is 2.5\ifmmode…

Théorie du traînage magnétique des substances massives dans le domaine de Rayleigh

Louis Néel1950-01-01Journal de physique

Ce travail est consacré à l'étude théorique des lois du traînage magnétique des substances massives dans des champs magnétiques faibles vis-à-vis du champ coercitif, c'est-à-dire dans le domaine de Rayleigh. On suppose que les fluctuations thermiques permettent aux parois de séparation entre les domaines élémentaires…

The Influence of Nuclear Structure on the Hyperfine Structure of Heavy Elements

Aage Bohr、V. F. Weisskopf1950-01-01Physical Review

The influence on the h.f.s. of the finite size of the nucleus is considered and the effect is calculated for simple models of the nuclear magnetism. It is pointed out that the distribution of magnetic dipole density over the nuclear volume may vary greatly from nucleus to nucleus depending on the relative contribution…
