STRUCTURAL, MAGNETIC, AND ELECTRICAL-PROPERTIES OF THE NEW TERNARY CEPDIN2

CePdIn2 is found to crystallize in the orthorhombic space group Cmcm ( Z = 4) with a = 4.6210(9) Angstrom, b = 10.694(2) Angstrom, and c = 7. 455(2) Angstrom. Single crystal X-ray data were refined to R(1) = 0.04 59 (wR(2) = 0.0666), with 255 independent reflections and 16 variables . The structure adopts the BRe3 structure type and is the first known Ce-containing member. Magnetic measurements indicate that CePdIn2 unde rgoes a ferromagnetic phase transition with a T-c near 10 K. The elect rical resistivity of CePdIn2 shows metallic behavior with a small anom aly at the magnetic phase transition. (C) 1996 Academic Press, Inc.
