In the search of an experimental realization of quantum spin liquid phases we have synthesized polycrystalline samples of Ba3NiSb2O9 under high pressure-high temperature conditions. Combining X-ray powder diffraction, neutron powder diffraction and precession electron diffraction we show that the obtained phase isn't hexagonal as reported in the literature, but trigonal. This new structure shows triangular Ni planes, but only in domains of sizes of the order of 10 nm. It therefore is still…

Nature of the randomness-induced quantum spin liquids in two dimensions.
TLDR
Frustration in a wide sense, not only the geometrical one but also including the one arising from the competition between distinct types of interactions, play an essential role in stabilizing this {\it frustrated\/} random singlet state.
Randomness-Induced Quantum Spin Liquid Behavior in the s = 1/2 Random J1–J2 Heisenberg Antiferromagnet on the Honeycomb Lattice

TLDR
The honeycomb lattice antiferromagnet Ba(3)CuSb(2)O(9) lattice shows two characteristic energy scales, including a field-dependent crossover to exponential low-temperature behavior, implying gapped magnetic excitations.

TLDR
Ba3CuSb2O9, which is magnetically anisotropic at the atomic scale but curiously isotropic on mesoscopic length and time scales, is found to have a broad spectrum of spin-dimer–like excitations and low-energy spin degrees of freedom that retain overall hexagonal symmetry.
