摘要：

Measurements of the macroscopic properties have indicated that the bond-disordered spin-gap system (CH3)(2)CHNH3-Cu(ClxBr1-x)(3) is gapless when x is between 0.44 and 0.87. Using muon spin relaxation to investigate the microscopic properties of a sample with x = 0.35, we observed a dynamical spin fluctuation, whose characteristic frequency decreased with decreasing temperature, indicating a magnetic ground state.
