【 摘 要 】

We report on the low-temperature physical properties of a novel compound Ce11Pd4In9 that crystallizes with the orthorhombic Ce11Pd4In9-type crystal structure (space group Cmmm). The compound exhibits ferromagnetic ordering at T-c = 18.6 K and an order-order transition at T-t approximate to 1.6 K, as inferred from the low-temperature magnetic susceptibility, heat capacity and electrical resistivity data. In the paramagnetic region, the electrical transport in Ce11Pd4In9 is dominated by Kondo effect. Below T-c, a distinct contribution due to ferromagnetic spin waves dominates the electrical resistivity data, while at the lowest temperatures, the electrical transport and thermodynamic properties are governed by strong electron-electron correlations. The features observed conjointly hint at strongly correlated ground state in Ce11Pd4In9.
