Abstract
The structural, magnetic, and thermodynamic properties of a new plutonium based compound, Pu2Pt3Si5, are reported. Single crystals produced by a Sn-flux technique have been analyzed showing a ferromagnetic behavior at 58 K. Pu2Pt3Si5 crystallizes in the U2Co3Si5-type orthorhombic Iabm structure (72) with atomic parameters a = 9.9226(2) à , b = 11.4436(2) à and c = 6.0148(1) à . The effective (μ_eff ~0.74 μ_B) and saturated (μ_sat ~0.32 B/Pu) moments as well as the Sommerfeld coefficient (γ_e ~2 mJ.mol-1.K-2/Pu) could point towards 5f localization in this material.
