Résumé
L'aimantation des alliages DyAg2 et DyAu2 est mesurée à des températures de 4,2° à 300 °K et dans un champ magnétique jusqu'à 100 kOe. On trouve que DyAu2 et DyAg2 sont antiferromagnétiques. Dans le cas de DyAu2 il y a une discontinuité dans la courbe susceptibilité-température. A 4,2 °K, l'aimantation croît en deux sauts avec le champ magnétique. Cette variation en deux sauts disparaît graduellement avec l'élévation de la température. Ce résultat peut s'expliquer en considérant un changement de la structure des spins.


Abstract
The magnetization of compounds DyAu2 and DyAg2 was measured at temperatures between 4.2° to 300 °K and under the magnetic field up to 100 kOe. Both compounds were found to be antiferromagnetic. In DyAg2, spin flopping occurred at low temperature. In DyAu2, a jump at 25 °K in the susceptibility-temperature curve was observed. At 4.2 °K, the magnetization increased in two steps with magnetic field. Such stepped transformation gradually blurred with rise of temperature till it vanished above 25 °K. These facts may be interpreted as an antiferromagnetic structture change.





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.
