High field magnetization study and analysis of magnetic interactions in Dy2Fe17-xGax (x=5-8) compounds
Description
High field magnetization measurements (up to 38 T) 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
