Single crystals of Gd117Ni56Sn104 have been synthesized by a eutectoid (Gd/Ni) flux. The compound crystallizes in the space group Fm-3m with the lattice parameter a = 30.025(2) � and V = 27,068.4(6) �3. The unit cell contains 1,106 atoms with 23 unique atomic positions consisting of 8 Gd, 6 Ni, and 9 Sn atoms, comparable to Gd117Co56Sn112 that exhibits one of the lowest lattice thermal conductivity in a bulk solid (?L = 0.28 W/(m�K)). In this presentation, I will discuss the structural model, magnetization, and electrical properties of Gd117Ni56Sn104.
