Abstract

In this letter, we report on the single crystal growth and physical characterization of the distorted kagomé system Pr₃Ga₅SiO₁₄. It is found that at zero magnetic field the system shows no magnetic order down to 0.035 K and exhibits a T² behavior for the specific heat at low temperatures, indicative of a gapless 2D spin liquid state. Application of an applied field induces nanoscale islands of ordered spins, with a concomitant reduction of the T² specific heat term. This state could be a possible ferro-spin nematic ordering stabilized out of an unusual spin liquid state.
