A comparison of the structure and localized magnetism in Ce2PdGa12 with the heavy fermion CePdGa6

Abstract Single crystals of Ce 2 PdGa 12 have been synthesized in Ga flux and characterized by X-ray diffraction. This compound crystallizes in the tetragonal P 4 / nbm space group, Z = 2 with lattice parameters of a = 6.1040 ( 2 ) A and c = 15.5490 ( 6 ) A . It shows strongly anisotropic magnetism and orders antiferromagnetically at T N ∼11 K. A field-induced metamagnetic transition to the ferromagnetic state is observed below T N . Structure–property relationships with the related heavy-fermion antiferromagnet CePdGa 6 are discussed.
