摘要：

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)(3) with 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 H-c < H < H', which separates the spin liquid phase from the unconventional Bose-Einstein condensation phase. The observed finite value of boson compressibility (dM / dH) and lack of field-induced three-dimensional long-range order are consistent with the theoretical prediction.
