Crystal structure and electrical resistivity studies of intermetallics

Abstract: Synthesis and X-ray analysis (300 K) of a new series were performed. The lattice parameter is considerably reduced with x. Electrical resistivity for the intermetallic series was measured in a wide temperature range and the parameters characterising the dependence of resistivity on temperature and composition were determined. The magnetic part of the resistivity was used to estimate Curie temperatures. The Curie temperature is strongly increased as a result of Mn/Co substitution. The obtained -results are related to the data known for the and series. [Copyright &y& Elsevier]
