Description:
We present the results of muon-spin spectroscopy ( μ + SR) measurements on the molecular spin ladder system (Hpip) 2 CuBr 4(1− x ) Cl 4 x , [Hpip = (C 5 H 12 N)]. Using transverse field μ + SR we are able to identify characteristic behaviour in each of the regions of the phase diagram of the x = 0 strong-rung spin ladder system (Hpip) 2 CuBr 4 . Comparison of our results to those of the dimer-based molecular magnet Cu(pyz)(gly)(ClO 4 ) shows several common features. We locate the crossovers in partially disordered (Hpip) 2 CuBr 4(1− x ) Cl 4 x ( x = 0.05), where a region of behaviour intermediate between quantum disordered and Luttinger liquid-like is identified. Our interpretation of the results incorporates an analysis of the probable muon stopping states in (Hpip) 2 CuBr 4 based on density ...
