dc.description.abstractX-ray diffraction, crystal structure, magnetization, and heat capacity results are presented for the rare earth chalcogenide ternary system PrCu₀.₄₅Te₂ and its non-4⨍ analogue LaCu₀.₄₀Te₂. The crystal structure of PrCu₀.₄₅Te₂ is characterized by chains of edge and corner-sharing CuTe₄ tetrahedra and Pr centered in polyhedra comprised of Cu and Te. The Cu site is partially occupied and exhibits signatures of local disorder. Magnetic susceptibility measurements show a Curie-Weiss temperature dependence consistent with a Pr³⁺ state. No magnetic ordering is observed down to 1.8 K, but the negative Curie-Weiss temperature suggests an antiferromagnetic exchange interaction. Importantly, the low temperature heat capacity of PrCu₀.₄₅Te₂ is strongly enhanced by comparison to LaCu₀.₄₀Te₂, suggesting that there is a build-up of entropy that is associated with the 4f-electrons from the Pr³⁺ ions. These features reveal possible spin frustration behavior and introduce this family of materials as a template for studying new phenomenon.
