Relation entre la constante d'anisotropie et la loi d'approche à la saturation des ferromagnétiques

Louis Néel1948-01-01Journal de physique

Quand le champ H croît, l'aimantation J d'un ferromagnétique cubique polycristallin tend vers la saturation Js selon la loi d'approche [FORMULE] et une théorie actuellement admise montre que b est égal à [FORMULE] où K est la constante d'anisotropie. L'auteur montre que cette théorie n'est pas correcte car elle a été…

Electrical Insulation Deterioration Treated as a Chemical Rate Phenomenon

T. W. Dakin1948-01-01OpenAlex

The basis is presented for a more accurate interpretation of the results of physical type tests to measure the thermal aging of insulation together with a more accurate method of applying the results of such tests to predicting insulation deterioration in practice. Since the observed physical changes during thermal ag…

On the Theory of Ferromagnetic Resonance Absorption

C. Kittel1948-01-01OpenAlex

The theory of ferromagnetic resonance absorption previously developed is extended to include the effect of the shape of the specimen and, in the case of a single crystal, the effect of crystal orientation. The resonance condition may be written ${\ensuremath{\omega}}_{0}=\ensuremath{\gamma}{H}_{\mathrm{eff}}$, where $…

Kinetics and Optimum Phenomenon of Vulcanization

B.A. Dogadkin、B. Karmin、I. I. Gol'berg1947-12-01Rubber Chemistry and Technology

Abstract The fundamental process of vulcanization consists in the combination of rubber with a vulcanizing agent : sulfur, sulfur monochloride, etc . The kinetics of this process may be expressed by monotonous curves. These may be interpreted either as the result of the heterogeneous character of the reaction or as th…

Detergency Studies

William P. Utermohlen、E.L. Wallace1947-12-01Textile Research Journal

A survey of the literature and the practice of detergency as applied to textiles has indicated that the manufacture of successful detergents has progressed further than has the fundamental science of detergency. Many of the basic factors in soiling of textile fibers and fabrics, and in cleaning of the soiled materials…

WATER CONTENT AND INFRARED TRANSMISSION OF SIMPLE GLASSES*

Anna J. Harrison1947-12-01Journal of the American Ceramic Society

A bstract Since glasses, which are high in silica or boric oxide content, have high absorption in the region of 2.7 to 3.0 microns, a study of the transmission characteristics of several simple glasses has been made. Measurements of a variety of commercially available samples (5 mm. thick) of fused silica showed absor…

The generation of electrical energy from thermal energy by thermoelectric means cannot be accomplished with thermocouples made of the available alloys generally used for temperature measurements, their efficiency being less than one percent. A review of the theoretical efficiency calculations shows that higher efficie…

This Subcommittee was organized in November 1941. It first selected the areas in which the terminology of sediments was confused and needed clarification, and drew up preliminary definitions to serve as a basis of discussion. These definitions were then distributed as widely as possible among the persons in this count…

The effective permittivity of two-phase systems

D. F. Rushman、M. A. Strivens1947-11-01Proceedings of the Physical Society

The effective permittivity of samples of barium titanate with porosities up to 40% v/v. has been determined, and an explanation given in terms of Wiener's mixture law. It is shown that the values of the form factor in this law can only be predicted with certainty over the ranges 0-30% and 70-100% porosity, and takes u…
