Description Ba3IrTi2O9 crystallizes in a hexagonal structure consisting of a layered triangular arrangement of Ir4+(J(eff) = 1/2). Magnetic susceptibility and heat capacity data show no magnetic ordering down to 0.35 K in spite of a strong magnetic coupling as evidenced by a large Curie-Weiss temperature theta(CW) similar to -130 K. The magnetic heat capacity follows a power law at low temperature. Our measurements suggest that Ba3IrTi2O9 is a 5d, Ir-based (J(eff) = 1/2), quantum spin liquid on a two-dimensional (2D) triangular lattice.
