Abstract

The synthesis and characterization of Ba3CuSb2O 9, which has a layered array of Cu2+ spins in a triangular lattice, are reported. The magnetic susceptibility and neutron scattering experiments of this material show no magnetic ordering down to 0.2K with a θCW=-55K. The magnetic specific heat reveals a T-linear dependence with a γ=43.4mJK-2mol-1 below 1.4K. These observations suggest that Ba3CuSb2O9 is a new quantum spin liquid candidate with a S=1/2 triangular lattice.
