Abstract

A new compound, CePdGa6, and its isostructural analog, LaPdGa6 have been synthesized by flux growth and characterized by single-crystal X-ray diffraction. The compounds adopt a tetragonal structure with P4/mmm space group, Z=1. The lattice parameters for CePdGa6 are a=b=4.350(3) Å and c=7.922(6) Å and a=b=4.3760(3) Å and c=7.9230(5) Å for LaPdGa6. Magnetic and thermal measurement have revealed that CePdGa6 is a heavy-fermion with the specific heat coefficient γ∼300 mJ/molK2 and Ce f moments order antiferromagnetically along c-axis at TN=10 K. Reconfiguration of spin occurs at 5 K to induce a ferromagnetic component only in the a-b plane. This strong anisotropy in the magnetism might be related to its unique layered structure. © 2003 Elsevier Inc. All rights reserved.
