Abstract
Sr2CuTe0.5W0.5O6 is a square-lattice magnet with superexchange between S=12Cu2+ spins mediated by randomly distributed Te and W ions. Here, using sub-K temperature and 20 μeV energy resolution neutron scattering experiments we show that this system transits from a gapless disorder-induced spin liquid to a new quantum state below Tf=1.7(1)
