Abstract

High field magnetization measurements (up to 38T) were carried out at 4.2 K on "free powder" samples from Dy2Fe17-xGax (x = 5-8) compounds. The data were used to evaluate the microscopic exchange parameter, JDyFe. Its value was also obtained by mean-field analysis of Curie temperatures, Tc, in agreement with the high-field data. The obtained results reveal an increase of JDyFe above x = 6 that can be correlated with the observed change in Tc vs. x for Dy2Fe17-xGax compounds and their counterparts with Y. © 2001 Published by Elsevier Science B.V.
