We report the single crystal study of the bulk magnetization and neutron scattering measurements on a quantum S=1/2 spin ladders system IPA-Cu(Cl0.95Br0.05)3with quenched disorder. In zero field, the disordered spin liquid phase is preserved as in pure IPA-CuCl3. Due to the bond randomness, a different Bose glass phase was directly observed in Hc<H<H', which separates the spin liquid phase from the unconventional Bose-Einstein condensation phase. The observed finite value of boson… Expand
