Crystal Structure and Transport Properties of Two New Compounds : SmPt_3B and GdPt_3B

摘要

Two new compounds, SmPt_3B and GdPt_3B have been synthesized for the first time. The powder X-ray diffraction at room temperature reveal that the compounds essentially form in single phase having the CePt_3B type crystal structure (space group Ρ4mm). The electrical resistivity measurements show metallic behavior and indicate that these compounds order antiferromagnetically at low temperatures.
