Abstract

We report on synthesis, crystal structure and physical properties of the isotypic compounds YbPdSn₂ and EuPdSn₂ crystallizing in the MgCuAl₂-type structure. In both stannides a divalent state of respective rare earth element was found from analysis of the magnetic susceptibilities. Whereas in YbPdSn₂ only weak paramagnetic behaviour is observed, in EuPdSn₂ a long-range magnetic phase transition occurs at 12.5 K with complex magnetic behaviour evidenced by magnetic susceptibity and specific heat measurements. Under the influence of magnetic field, the magnetic behaviour was found to evolve from an antiferromagnetic to a ferromagnetic state as a consequence of a re-arrangement of magnetic moments.
