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

Single crystals of Ce2PdGa12 have been synthesized in Ga flux and characterized by X-ray diffraction. This compound crystallizes in the tetragonal image space group, image with lattice parameters of image and image. It shows strongly anisotropic magnetism and orders antiferromagnetically at TN∼11 K. A field-induced metamagnetic transition to the ferromagnetic state is observed below TN. Structure–property relationships with the related heavy-fermion antiferromagnet CePdGa6 are discussed.
