Résumé
Le présent article décrit la relaxation Orbach avec "phonon bottleneck" en fonction du champ et de la concentration en ions Ce dans LaMN . Les résultats prouvent que le temps de vie des phonons est ≈10-8s, indépendament la température entre 1,5 et 4,2 K.
Abstract
The bottlenecked Orbach relaxation process was studied as a function of field and concentration of Ce ions in LaMN. It is shown that the lifetime of the phonons in the relaxation equals ≈10-8s, independent of temperature between 1.5 and 4.2 K.
