Abstract

Measurements of the macroscopic properties have indicated that the bond-disordered spin-gap system (CH₃)₂CHNH₃-Cu(Cl_xBr_1-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.
