Abstract

We report the electrical and magnetic properties of the hexagonal NdAuGe, through the measurement of X-ray diffraction (XRD), electrical resistivity ((T)), magnetic susceptibility ((T)) and magnetization ((0H)). XRD data indicate a hexagonal NdPtSbtype structure with space group P63mc. Result of electrical resistivity shows a metallic – like behavior below 150 k and a broad curvature above 150 k. The law temperature (T) data indicate the onset of a magnetic transition. (T) data at low temperature in zero field-cooled (ZFC) indicates a magnetic phase transition at temperature TN =7.8 k. The high temperature (T) data follow the Curie – Weiss relation and give effective moment value eff slightly reduced from the expected value 3.62 B of the free Nd+3 -ion. ZFC and FC (field cooling) (T) shows a bifurcation below Tf = 13 k.
