Résistivité électrique d'un alliage Au Cu

M. C. Anquetil

Centre d'Études Nucléaires de Saclay, France


Abstract
An alloy presenting a periodic antiphase structure is studied, and its electrical resistivity is determined over a temperature range from 20 to 500°C. The transition temperatures observed either from X-rays or resistivity measurements are in good agreement. At each transition temperature one notes important variations of resistivity and noticeable slowing down of the rate of reaching equilibrium.


Résumé
Nous étudions un alliage présentant aux rayons X une structure à antiphases périodiques et déterminons la variation de la résistivité électrique en fonction de la température entre 20 et 500°C. Les températures de transition déterminées par rayons X coïncident avec celles observées ici. L'apparition de chaque nouvelle phase se manifeste par d'importantes variations de résistivité, et par de très faibles vitesses de mise à l'équilibre.

What is OpenURL?

The OpenURL standard is a protocol for transmission of metadata describing the resource that you wish to access. An OpenURL link contains article metadata and directs it to the OpenURL server of your choice. The OpenURL server can provide access to the resource and also offer complementary services (specific search engine, export of references...). The OpenURL link can be generated by different means.
  • If your librarian has set up your subscription with an OpenURL resolver, OpenURL links appear automatically on the abstract pages.
  • You can define your own OpenURL resolver with your EDPS Account. In this case your choice will be given priority over that of your library.
  • You can use an add-on for your browser (Firefox or I.E.) to display OpenURL links on a page (see http://www.openly.com/openurlref/). You should disable this module if you wish to use the OpenURL server that you or your library have defined.
