Neutron scattering experiments on a polycrystalline sample of the frustrated pyrochlore magnet Tb 2Ti 2O 7, which does not show any magnetic order down to 50mK, have revealed that it shows condensation behavior below 0.4K from a thermally fluctuating paramagnetic state to a spin-liquid ground state with quantum spin fluctuations. Energy spectra change from quasielastic scattering to a continuum with a double-peak structure at energies of 0 and 0.8K in the spin-liquid state. Specific heat shows an anomaly at the crossover temperature.
