Description
We have investigated the physical and magnetic properties of the hexagonal Kagome lattice structure compound Pr3Os4Al12 which crystallizes in the hexagonal Gd3Ru4Al12-type structure with space group P63/mmc (No. 194). The compound shows a long-range magnetic ordering of the Pr3+ moment at TC = 37 K as indicated by the temperature dependences of magnetic susceptibility, specificc heat and electrical resistivity. The magnetic ordering is associated with the frustration of the magnetic spins which are located on a triangular Kagome lattice. The electrical resistivity shows a spin-gap behavior below TC.
