Abstract
The magnetization of copper-cobalt alloys, from 0.6 to 3 %, abruptly quenched, has been measured down to 0.08 °K. A fair agreement with the Néel model of fine grained antiferromagnetics is shown. In high fields and especially at relatively high temperature, the substance behaves like an antiferromagnetic. At low temperatures, remanent magnetism may be interpreted as a particular kind of ferrimagnetism.

Résumé
On a mesuré l'aimantation jusqu'à 0,08 °K d'alliages de Co et de Cu de 0,6 à 3 %. On rend compte des propriétés par l'existence d'une interaction antiferromagnétique et on met en évidence l'intérêt du modèle de Néel (grains fins devenus ferrimagnétiques) pour l'interprétation des phénomènes observés (température de blocage, aimantation rémanente, etc...).

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.
