Structural and magnetic properties of the new Eu-Pd-Sn compound Eu <sub>3</sub> Pd <sub>4</sub> Sn <sub>13</sub>

Abstract

The ternary compound Eu₃Pd₄Sn₁₃ was synthesized by induction melting of the elements in a sealed tantalum crucible and characterized through their powder X-ray diffraction pattern and SEM. Based on laboratory X-ray powder diffraction data, the crystal structure of Eu₃Pd₄Sn₁₃ can be refined in the Yb₃Rh₄Sn₁₃-type structure with cubic symmetry (<italic xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">Pm</i>3<italic xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">n</i>). The possible presence of subtle symmetry lowering beyond the resolution of the present experiment cannot be ruled out. The magnetic properties were investigated by magnetic susceptibility, isothermal magnetization at different magnetic fields, and specific heat measurements. The trend of the inverse susceptibility as a function of temperature follows the Curie-Weiss plot with μ<sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">eff</sub> = 7.63 μB, in reasonable agreement with the theoretical value of Eu²⁺. A kink in the magnetic susceptibility curve is observed at about 5 K, which could indicate a complex interplay between antiferromagnetism and ferromagnetism.
