Résumé
La variation thermique du champ d'anisotropie a été determinée dans les composés du type R2Fe14B (R = Th, Y, La, Ce, Pr, Nd, Gd, Ho, Lu) à des températures, entre 4.2 K et la température de Curie. Dans les composés Nd2Fe14B et Pr2Fe14B on a observé une réorientation du spin.


Abstract
The temperature dependence of the anisotropy field was measured in various compounds of the type R2Fe14B (R = Th, Y, La, Ce, Pr, Nd, Gd, Ho, Lu) at temperatures between 4.2 K and the Curie temperature. In Nd2Fe14B and Pr2Fe14B a spin reorientation was found to occur below room temperature.
