Impurity effects in coupled-ladder BiCu2PO6 studied by NMR and quantum Monte Carlo simulations
L. K. Alexander, J. Bobroff, A. V. Mahajan +3
We present a 31P NMR study of the coupled spin 1/2 ladder compound BiCu2PO6. In the pure material, intrinsic susceptibility and dynamics show a spin gap of about . Substitution of…
Doping effects in the coupled, two-leg spin ladder BiCu2PO6
B. Koteswararao, A. V. Mahajan, L. K. Alexander +1
We report preparation, x-ray diffraction, magnetic susceptibility chi(T) and heat capacity Cp(T) measurements on the undoped samples as also samples with Zn-doped (S = 0) at Cu sit…
Supplementary material for "Impurity-induced magnetic order in low dimensional spin gapped materials"
J. Bobroff, N. Laflorencie, L. K. Alexander +3
In this supplementary material, we investigate further the impurity-induced freezing mechanism in a doped system of 3D weakly coupled ladders resembling Bi(CuZn)ZnP…
Impurity-induced magnetic order in low dimensional spin gapped materials
J. Bobroff, N. Laflorencie, L. K. Alexander +3
We have studied the effect of non-magnetic Zn impurities in the coupled spin-ladder Bi(Cu1xZnx)2PO6 using 31P NMR, muSR and Quantum Monte Carlo simulations. Our results show that t…
