Crystal structure and electrical resistivity studies of Gd(Fe1−x Cox)2 intermetallics
چکیده انگلیسی

From X-ray analysis (295 K) it was found that the cubic, MgCu2MgCu2-type, Fd3mFd3m crystal structure appears across the Gd(Fe1−x Cox)2 series. Electrical resistivity measurements for the Gd(Fe1−x Cox)2 intermetallics were performed in a wide temperature region and the parameters characterizing the resistivity dependence on temperature and composition were determined. The differential of the electrical resistivity against temperature was used to estimate Curie temperatures. The Curie temperature versus x, high and moderately increasing in the iron-rich area, rapidly drops in the cobalt-rich region. The obtained results are compared with the data known for the Dy(Fe1−x Cox)2 series. The Curie temperature is related to both the number of 3d electrons and the de Gennes factor.
