    • Impurity effects in coupled-ladder BiCu(2)PO(6) studied by NMR and quantum Monte Carlo simulations 

      ALEXANDER, LK; BOBROFF, J; MAHAJAN, AV; KOTESWARARAO, B; LAFLORENCIE, N; ALET, F (AMER PHYSICAL SOC, 2010)
      We present a (31)P NMR study of the coupled spin 1/2 ladder compound BiCu(2)PO(6). In the pure material, intrinsic susceptibility, and dynamics show a spin gap of about Delta approximate to 35-40 K. Substitution of nonmagnetic ...
    • Impurity-Induced Magnetic Order in Low-Dimensional Spin-Gapped Materials 

      BOBROFF, J; LAFLORENCIE, N; ALEXANDER, LK; MAHAJAN, AV; KOTESWARARAO, B; MENDELS, P (AMER PHYSICAL SOC, 2009)
      We have studied the effect of nonmagnetic Zn impurities in the coupled spin ladder Bi(Cu(1-x)Zn(x))(2)PO(6) using (31)P NMR, muon spin resonance (mu SR), and quantum Monte Carlo simulations. Our results show that the ...
